Gallery integration with WordPress Login

I searched everywhere looking for a gallery (not a plugin) which can be well integrated with wordpress but….it seems it doesen’t exist!
I mean, I tryed nextgen, plogger and so on but…they don’t use the same wordpress login and also don’t support user upload.

The best gallery around if you consider features is 4images, but it doesn’t have any wordpress integration..

Is there a complete gallery to use with wordpress or just using the same wordpress login?
Please help!!!!
Many thanks
