Hi

I have been trying to find the description page for latex math images. Here is an example of such an image: http://upload.wikimedia.org/math/f/6/a/f6ac8632c237011599f300e62d916859.png obtained from the page http://en.wikipedia.org/wiki/Acid

However I am unable to find the description page for such images. I tried http://en.wikipedia.org/w/api.php?action=parse&format=xml&page=File:... and that resulted in an xml with error code="missingtitle" info="The page you specified doesn't exist"

I have also tried http://en.wikipedia.org/wiki/File:F6ac8632c237011599f300e62d916859.png Which says the file does not exist.

I am trying to get the licensing information for images, and then try to download them. Any suggestions or pointers are welcome.

Thanks Priyank
