Hi,
I make a gallery where artists can have their own sub-galleries and upload photos:

I have made a gallery named "Photography" (the owner is me) and 5 sub-galleries, one for every artist, inside the "Photography" gallery.
I want every artist to be able to change the description and upload photos  ONLY to his own sub-gallery.

All 5 artists belong to the "registered" user group and their galleries' acl Permissions don't allow to other registered users to upload photos etc.

Normally, a registered artist cannot upload photos in any other sub-gallery except his.

Problem 1
This works (almost) fine  in firefox but not in IE7 where any registered artist can upload to any other artist's sub-gallery he wants.

Problem 2
Additionally, in firefox the  situation works fine, every artist can upload photos only to his sub-gallery, he also can create sub-galleries only inside his sub-gallery.
The problem  is that if he clicks on an existing sub-gallery to edit it then he is able to save his gallery to any other artist's gallery

Are we doing something wrong?

thanx:) thanx:) thanx:)
