Also there are Special:FilePath and thumb.php. I'm not sure how this affects caching though. http://commons.wikimedia.org/wiki/Special:FilePath/Example.svg http://commons.wikimedia.org/w/thumb.php?f=Example.svg&w=420 -Liangent On Jul 3, 2014 4:50 AM, "Emilio J.

For a 200px thumb: https://upload.wikimedia.org/wikipedia/commons/thumb/x/xy/File_name.ext/200… The SVG files are a special case, therefore .png is appended to .ext, being .ext.png. For SVG doesn't mind to use big thumb sizes, but when file is JPG, don't try to generate a thumb bigger than the original file or you will get a beautiful error.

I can easily use it to build a link to the Commons page fo rthat image. * But how do I get the raw image URL? * And can I also get the raw URL of a small-scale (thumbnail) image? I would like to beautify my Wikidata applications to show some images. I know this is more of a general MediaWiki question, but it is much more relevant in Wikidata, so I am posting it here first. I guess somebody has already solved this since we have images in various Wikidata-based applications and gadgets.
