Good point. Anyway, PNG is the format suggested in the spec and one
could guess that they did some investigation on pros and cons of
various image formats before deciding on PNG...

Sorry, that was probably a sloppy description from me. What they
suggest is to generate the URL/URI (which is it?) to the file, so:




After that they compute the MD5 sum for this value and use that as
thumbnail file name. Also, some information is added to the PNG file
(original file name and some more stuff). Read the full spec for more
information, I better not try to explain it myself again... :)
