Gallery for all Registered Users

I’m looking for suggestions on how to create a gallery page that is open to all of my registered users (this is an invite only site).

Ideally, if the world were perfect I’d have a Gallery page on the menu and any user can go to the page and upload a photo (with description, title, etc).

Several of my users are not tech savvy, so I don’t want to have them messing around with anything other than hitting an “upload image” button, really this needs to be so easy my grandma who uses Facebook can figure it out.

Ok…it would also be nice if I could click on an image and be able to see all the images that user uploaded.

I’m playing around a bit with NextGen but it really seems too complicated for what I’m looking for.

Suggestions appreciated.

Thanks!
