I’m looking for a user friendly image gallery which would allow the following:
Users can upload images, title them and add a description at the time of uploading, without having to go back in to edit it.
Commenting on images.
No need for images held for moderation before publishing.
A central gallery for images to be uploaded to, (not necessary for users to have to have their own galleries).

I tried BP-Gallery, but users found it annoying that they could only add a description by putting it as a comment and could not title their images after uploading.

I’m using WP 3.4.1, BP 1.5.6

Any input would be greatly appreciated.
