probably been discussed before...but
users need to have their own private space to upload personal images (for profile, avatar use etc), without having to create subalbums and alike
there should be a toplevel album called (for example) 'Private User Albums' and within users may add, edit, and delete their own albums in their user sub-album
browsing this toplevel album would be like browsing a memberlist with highlighted user pics
this IS a standard feature for many competitive albums out there...unfortunate they lack many of galleries other great features ;)
