Even though Zenphoto is a great tool, it was initially designed like a blog where the admin would manage all aspects of the media. in the light of many plug-ins now added, its imperative to shift the paradigm to the client in the context of media & rights management ie album creation, uploading and rights management which are fundamental. Users are perplexed not to find an 'upload' & 'album' pages upon registering as is common with other gallerys including youtube. In addition to the feature of album passwords, allow albums to be related to the 'user' using the Database ('owner' field - zp_albums). This will make ZP simple and equal to the best.
Thus in a nutshell
1) All registered users should have 'upload' & 'album' pages upon registering by default
2) The admin should continue exercising authority on the above to curtail abuse
