Using IrfanView for image slideshows

3 Replies

The other evening, I went to see my friend Peter Shirley talk to the Sandwell Valley Naturalists Club about the wildlife he saw in Canada. Pete is @PeteWestBrom on Twitter and you should follow him, and read his , if you’re interested in nature, wildlife conservation, or green issues.

He mentioned to me that he was looking for some software to display images in a slideshow, but sorted into his preferred order, rather than by datestamp or file name. He wanted something less cumbersome than PowerPoint or its free equivalent in LibreOffice, Impress. I said I knew of something that would do the job, and would send him details. But on the principle of responding to technical questions openly, in public, in order to more widely share and disseminate knowledge, I’m posting the answer here, and I’ll send him a link to this post.

For some time, I’ve used the excellent programme, an image viewer which also serves as a lightweight, but nonetheless powerful, image editor. It’s not Photoshop (nor the free equivalent, GIMP), but it’s great for cropping, rotating, changing contrast or brightness, and other similar tasks, which it can also do on a batch basis. It’s free for non-commercial use, for Windows. Its author, Irfan Skiljan, is also very responsive to user requests, and the programme has several features which he’s kindly added at my request.

And it has a slideshow feature.

IrfanView slideshows can be used for talks and presentations like Pete’s, or be left unattended, as a “carousel” or “kiosk” style display. To make one, first, download and install IrfanView, and any of its various plug-ins you might use (I simply download and install the full set of plugins, in one file).

Next, to set up a slideshow, use the IrfanView File menu and select Slideshow. You’ll see a dialogue like this (taken from the current version at the time of writing, v4.36):

IrfanView Slideshow dialogue

Use the top-right quarter to navigate to the images you wish to use. You can select them in batches and use the add button or double click on them to add them to the list, which will appear in the bottom-right corner, one at a time. Once you have your list of files, you can use move up, move down or sort, to carry out those actions, and you can remove files that are no longer needed.

You can also include mp3 files, to have music, or other audio, played along with your images. That could even be a narration.

In the top left section, chose whether to have automatic transitions, based on a timer, or a keyboard/ mouse action, or random transitions. Below that, select your other options (I won’t list them here, but you can play around with them, to suit your needs — they should be reasonably self-explanatory).

Use the “play” option to run through the presentation and make sure you’re happy with it. You can reorder, add or remove images at any time.

When you’re happy with the slideshow, you can save the running order to a text file (and later reopen it), though that assumes that the images remain on your machine, in the original folder(s). Alternatively, you can burn the whole show to a DVD, or create an executable file including the images and running order.

And that’s it. What’s not to like?

Politician pin ups – open-licensed pictures, please

20 Replies

Politicians, like visits to the dentist and taxes, are a necessary evil. We all moan about them, but someone has to take care of the machinery of state.

So it’s important that we hold them to account, and elsewhere document their activities in a neutral way. Hyperlocal bloggers do the former, and the latter takes place on Wikipedia, and on sites like the excellent OpenlyLocal (both of whose content is open-licensed).

To illustrate such articles, bloggers and Wikipedians need photographs of the politicians (and senior officers). While it’s possible for individuals to take such pictures (and even open-license them, as I described previously), it would be better if such pictures were available from official channels. Such organisations already take or commission professional quality shots and make them available to the press. If they don’t already, they should make sure that their contract with photographers pays for full rights, enabling open-licensing.

I recently asked Birmingham City Council’s press office to make their pictures of members of BCC’s cabinet available under an open licence, and, to their credit, they did so. I was then able to use one of them on :

Some might ask “but what if the pictures are misused, to misrepresent those people”. Well, if someone’s going to do that, then they won’t bother about copyright anyway, and other laws (libel, human rights) already enable redress.

So come on all you councils, civil service departments, police forces/ authorities and so on — let us have pictures of your elected members and senior officers, free (i.e. with no “non-commercial” or “no derivatives” restrictions) for reuse on our blogs, Wikipedia and other sites. Major companies, too, could do this for their most-public board members.

Then there’s all public bodies’ other photographs. After all, West Midlands Police kindly agreed to my request to open-license the fantastic aerial shots from their helicopter…

Open-licensing your images. What it means and how to do it.

22 Replies

I do a lot of editing on Wikipedia. Sometimes I approach someone connected with a subject I’m writing about (or the subject themself), and ask them to provide an “open licensed” image. In other words, an image whose copyright they own, but given a licence which allows anyone to reuse it, even for commercial purposes.

With a few exceptions, only images made available under such licences can be used on Wikipedia.

Creative Commons

The commonest form of open licence is Creative Commons — a set of legalistic prose documents which cover various ways of licensing images.

Some Creative Commons include “non-commercial” (“NC”) clauses; these are incompatible with Wikipedia, because people are allowed to reuse content from Wikipedia in commercial situation, such as in newspapers or in apps which are sold for use on mobile devices (provided they comply with other licence terms). The same applies to “no derivatives” (“ND”) clauses, which mean that people cannot edit, crop, recolour or otherwise change your picture when reusing it.

The Creative Commons licences compatible with Wikipedia are:

  • Attribution Creative Commons (CC-BY)
  • Attribution-ShareAlike Creative Commons (CC-BY-SA)

In which:

  • “Attribution” means that the copyright holder must be given a credit
  • “ShareAlike” means that if someone uses your picture, anything made with it must have the same licence

It’s important that anyone open licencing an image understands what that means. For example, Wikimedia (the organisation behind Wikipedia) suggests that people donating images are asked to agree to the following:

  • I acknowledge that I grant anyone the right to use the work in a commercial product, and to modify it according to their needs, as long as they abide by the terms of the license and any other applicable laws.
  • I am aware that I always retain copyright of my work, and retain the right to be attributed in accordance with the license chosen. Modifications others make to the work will not be claimed to have been made by me.
  • I am aware that the free license only concerns copyright, and I reserve the option to take action against anyone who uses this work in a libelous way, or in violation of personality rights, trademark restrictions, etc.
  • I acknowledge that I cannot withdraw this agreement…

(and yes, that wording has a CC-BY-SA licence!)

Which is the best licence to use?

That depends on the circumstances, but CC-BY-SA fits most cases, giving the re-user the greatest flexibility, while protecting the copyright holder’s right to be recognised.

So, how do I open-licence an image?

There are a variety of ways to open-licence an image. Here are some of the commonest:

  • Upload your images to Wikimedia Commons, the media repository for Wikipedia and other Wikimedia projects
  • Upload your images to Flickr, specifying one of the above open licences
  • Upload your images to your own website, with a clear and unambiguous statement that they are under a specified open licence

My images are on Flickr, how do I change the licence?

To open-licence a single image in Flickr:

Selecting an open licence in Flickr's pop-up dialogue

  • View the specific image
  • Under “Owner settings”, alongside current licence setting (perhaps “All Rights Reserved”), click “edit”
  • In the pop-up window, check one of the compatible licences
  • Save

[Postscript: My friend John Cummings wrote an equivalent guide for YouTube]

Won’t I lose money doing this?

the ingliston gorilla

Not necessarily. Some commercial photographers release low- or medium- resolution copies of their images, and sell high-resolution copies, but most people take images for personal purposes, which have no commercial value, and for which they will never be paid. Open-licensing them enables the community to benefit, at no cost to the photographer. Think of open-licensing your images as a way of giving back to the community which has given you so many open-source tools, without which the web would not work.

If this post has inspired you to openly-licence your images please let me know, in the comments.

And yes you can use other people’s open-licenced images, including many of mine, free. Help yourself!

Caveat

Yes, I know there are other open licences, and more complex use-cases. This is intended as a beginners’ guide. A competent lawyer will be able to provide you with legal advice. I offer more general advice to institutions wanting to open-licence their images or other content, or to work with the Wikipedia community, as part of my professional services.

Portrait with Brompton Bike

2 Replies

I had my portrait (or rather, several) taken yesterday, by , aka Dividenthal, as part of his project to record the cyclists of Birmingham.

We got in touch on the useful Birmingham Cyclists website.

I posed with my beloved Brompton bike, under Lancaster Circus Flyover (52.48598,-1.892513) and by one of my favourite statues, Hebe (52.484438,-1.892175), by (1966).

Thanks to Pete for permission to reproduce the pictures, which are his copyright, all rights reserved.

Sharing images openly is better than uploading to single sites

Leave a reply

Simon Whitehouse, blogging as part of his day-job with Digital Birmingham, suggests that to the History Pin website.

That’s a neat idea; it would be a collaborative move on behalf of the City (disclosure: they employ me, but these are my own thoughts), and would be of interest to the general public.

However, the time and effort spent doing do so would only be of use to that one site and its visitors.

A better solution, perhaps, would be for the City Council (and anyone making archives of images available in an open manner) to invest the equivalent effort in adding metadata (about the subject, location, date and licence, which should of course be open) to suitable images, and for third-party sites to then parse that metadata, and import the images. Of course, such an import could also be done by individuals, on an “as needed” (or more likely “as desired”) basis, as a crowd-sourcing activity.

Carved and painted stone coat of arms

My picture of the City of Birmingham's pre-1974 coat of arms, hosted on Flickr, where it has lots of lovely, rich metadata and an open licence

The question is — what is the best way to include such metadata — internal to the image, in a format like ? As scrapeabe text, on a page displaying the image, like Flickr’s metadata, such as tags? Or on such a page, but using a parsable , or as a separate resource, such as ? Or a combination of these?

And are any third-party sites already indexing or aggregating images and their metadata in this way? If not, why not? Do we have a chicken-and-egg problem?

Ian Emes’ ‘French Windows’ and Pink Floyd’s ‘One of These Days’ at Ikon

2 Replies

This evening, I went to the opening of a new exhibition at Birmingham’s Ikon gallery, ““.

The exhibition celebrates Ikon’s artistic programme from 1970 to 1978, and I particularly enjoyed Peter Sedgley‘s hypnotic Corona and David Hepher‘s No. 21.

David Hepher's 'No 21', painted in 1973, and Becky, who wasn't even born then.

But for me, as a Pink Floyd biographer, the highlight was undoubtedly the chance to see not only Ian Emes’ 1972 animation for the band’s One of These Days, projected onto the wall of a room the size of my living room (and in better quality than the YouTube version below), but also several cells from the animation, allowing close inspection. The film is accompanied by Pink Floyd‘s music (or is that vice versa?); sadly the sound system isn’t up to the job.

I had been told that my new book, Pink Floyd: The Music and The Mystery , would be on sale, but apparently there was a supply issue. Maybe soon?

Ian Emes will be giving a free talk on 18 August (booking essential); the exhibition itself runs until 5 September 2010.

Update: Spelling corrected; it’s “Emes” not “Eames”. Thanks to of Ikon for pointing that out. Sorry, Ian!

Update 2: I wrote a Wikipedia article about Emes.

Taxonomic machine tags

2 Replies

Images on Flickr (and other sites?) can be tagged with “machine tags“. For living things, these can convey taxonomic information. For example:

taxonomy:binomial=Larus melanocephalus

taxonomy:genus=Larus

Flickr collapses these to:

“larusmelanocephalus” and “larus“, but note that subtracting one from the other gives the specific epithet, “melanocephalus“.

For subspecies, use:

taxonomy:binomial=Larus glaucoides
taxonomy:genus=Larus
taxonomy:subspecies=Larus glaucoides kumlieni

and for other ranks:

taxonomy:class=Aves

Here’s an example: http://flickr.com/photos/pigsonthewing/2238938901/

Well, what are you waiting for? Tag away!
