I am working on something like this, but not with all those functions, but rather better integrated into the calendar, because the fotos are tied to events.

I don't mind helping if you can use my help and don't have very strict deadlines :)

i was in the middle of coding a gallery but i stopped coding so its just sorta sitting on my compy and since i will be very busy for next few months it will not be picked up. The gallery was one of my first works so the code isnt exactly clean but it was on its way to fully intergrating allowing it to transfer gallery items into posts etc. If anyone is interested in picking up my file and coding the rest(i personally find it a mess of code) just contact me.

Use photopost, it should be do everything you want to have. Only the source-code is not very well done if you want to have clean html-pages, but most people seems not to care about such things. ;-(
The installation could be better supported, but after the tenth installation you will know the tricks ;-)

I've seen a few threads on here about people wanting to reinvent the wheel. Thousands of man-hours went into developing PhotoPost and it does everything on your list: I really don't understand why you'd want to start from scratch. It would be far easier to take PhotoPost and modify it to suit your needs, or hire the PhotoPost developers to do a custom mod for you.

More scripts = better code, re-inventing the wheel is what made vBulletin what it is today ;)

I'm looking for something similar to this too. I've got pictures tied to events as well.

The easier way to go is probably to use vBulletin's existing functions and "fake" a gallery, where forums are categories, threads are images and posts are comments. It can save a lot of time, the only downside is you will have to heavily hack the vBulletin files (rather than create new scripts).

Here's a start. I've got about 10 hours into it now. I plan on adding many functions. Would welcome help.

Maybe this will help?
