No need for md5 hash calculations :-) In python the call to fileUrl() actually 'translates' the Commons image page name into the URL for the full size image file to download without having to provide any other information. Behind the scenes this actually uses the API to call a "query" returning "imageinfo". You may find a real example of API calls useful. Starting with the image title "Gay.jpg" [1] we can ask the API to tell us its properties by creating a call to API query [2], within the results (which you could ask for as xml or JSON) this returns us the URL link to the full sized image file which you can download. [3] Rather than full size, you can request a particular size, such as with a width of 100px [4]. In my script to query tineye.com to check for matches to mobile images as possible copyright violations, I only used thumbnails of width 300px, it saved a lot of bandwidth. :-) 1. http://commons.wikimedia.org/wiki/File:Gay.jpg 2. https://commons.wikimedia.org/w/api.php?action=query&titles=File:Gay.jpg&prop=imageinfo&iiprop=url 3. https://upload.wikimedia.org/wikipedia/commons/9/90/Gay.jpg 4. https://commons.wikimedia.org/w/api.php?action=query&titles=File:Gay.jpg&prop=imageinfo&iiprop=url&iiurlwidth=100 I would imagine that an introductory workshop should cover the basics of how to use the API and how to find parameters in the manual, this would be particularly useful for folks more comfortable programming in other languages that Python, or using other tools, and would still use all the features of the API to do interesting stuff.
