It looks like vBulletin 3 is going to include a feature that will allow a member to upload his/her own photo into his/her profile. This photo would then be displayed in the user's profile whenever someone views it.
However, I saw no mention of a centralized system wherein you could view
all photos; this is what my hack basically does.
Therefore, when vBulletin 3 comes out, if it's not already included by then, I intend to release a new Photo Gallery hack that will build on the built-in profile photo system that's built in to vB 3. This new hack will be a centralized page to see all photos, as is this current version, but it should be simpler and more user-friendly, since it uses the photos that users upload for themselves.
Let this serve as notice that, unless the vBulletin developers include this functionality in the release version, I hereby claim eminent domain over this idea, and kindly ask that nobody else work on the same idea.
