I noticed today that Google now indexes image description pages (see http://www.google.com/search?q=petersen+graph+site%3Acommons.wikimedia.org). Unfortunately, Google Images still doesn't find anything useful (see http://images.google.com/images?q=petersen%20graph%20site%3Acommons.wikimedia.org). I suspect the problem might be that on image description pages, the actual <img> tag has no useful attributes. Perhaps if the "title" attribute is set to the image's title, that will encourage better search engine indexing.
With r25335 Tim set the title attribute for the <a> tag to the imagename, when a caption was not given by the user. Should we do this for the image description page too? At the moment the rendered HTML looks like: <a href="/wikitest/images/d/d3/imagename.jpg"> <img alt="Image:Imagename.jpg" src="/wikitest/images/thumb/d/d3/Imagename.jpg/1024px-Imagename.jpg" border="0" height="223" width="1024"> </a>
It seems that both Bing and Google find plenty of relevant image results now. I don't think this bug is still an issue. We might consider closing it ?
