Hi, I have few questions: 1) "http://farm1.static.flickr.com/98/243417469_387520831a.jpg" In above link(1) "/98/" is server-id but is it a real folder? 2) "http://a479.ac-images.myspacecdn.com/images01/54/l_a0e19f2696e4abe238a450c31ba94856.jpg" In above link(2) are "/images01/" and "/54/" are real folders? 3) "http://images40.fotki.com/v1334/photos/2/2043/6426488/_DSC7719-th.jpg" In above link(3) are "/v1334/", "/photos/", "/2/","/2043/" and "/6426488/"are real folders? 4) "http://i368.photobucket.com/albums/oo125/christinabrinster/PANDA.jpg" In above link(4) are "/albums/", "/oo125/" and "/christinabrinster/" are real folders? So the main question is that is those sites use any folder(directory) structure?
