No, I'm using 4images 1.7.2 with the security fixes because I'm using a special integration to my vBulletin Forums, the sessions.php from 1.7.3 differs from the one of 1.7.2, thus I'm unable to update my 4images until a new, up to date Version of my integration mod is released.
I'm using the version from the first post in this thread, I didn't get the one from page 14 to work, I think that was the one you mentioned.
