The FS or a web or a ftp server is the "Server" conceptually. The UA (gimp) loads the whole Document (a file maybe containing multiple images) and interprets the fragment identifier locally -- according to the type of the document. This is more or less for what fragment ids where invented in the first place... There is also not more than on # needed. The uri would only clash if there are UAs who already have some widely accepted meaning for a fragment id in e.g. an animated gif. There are none. And if there were, I suppose it's quite probable that they would use the FID much the same way and not for e.g. addressing a coordinate in the image (or any other random stupid thing one could think of) jtl
