You know when on someone’s profile you see ‘View Photos of X (405)’ and you click to see them all and you can only see something like 340? Well there’s a way to see at least a few of those hidden pictures.
Get their facebook ID and go to: http://www.facebook.com/photos.php?subj=[Facebook ID]
You’ll now see a page that shows all the albums they’re tagged in. Unfortunately the photos that are in private albums are not clickable, but you can still enlarge that one thumbnail of that album. The filename of the thumbnail is something like: aXXXXXXXX_XXXXXX_XXXX.jpg and to access the fullsize image you just got to copy and paste that url into your address bar and change that little ‘a’ to an ‘n’.
This will only work on public profiles in your networks and it will not allow you to see every picture of them as they may have more than one picture in those private albums and you can only see one in the thumbnail
i seriously doubt facebook would fix this so go ahead and use it for however long you want
NOTE: I’m currently in the process of writing a greasemonkey script for the previously-announced hack and it should be finished soon
