User Based Image Admin

Hi, I’m using the WYSI-Wordpress plugin which allows my users to upload or link to pictures with the ease of writing an e-mail in a rich text editor..

However, in a community based site like mine (which is WP 1.5.2), I’ve noticed it’s not the best since all uploads get dumped into the same gallery, and so each of my authors is able to insert in images that have been uploaded by other authors.

Is there another rich text editor like this that allows people to insert in pictures, but keeps each authors uploads seperate? So that they can’t insert each others images?

Anyone know of one?
