Thanks, that's what I thought...
I guess I have to re-think my sitestructure.
I was hoping to use the power of the files&images-tab for the main-administrator and some custom uploadforms like subclasses of filefield or the filedataobjectmanager for the regular administrators. But let them both be able to edit at least the copyright-notice (a field added by dataobjectdecorator - since the copyright are quite important when using creative commons-images).
Since it seems not to be possible (or quite difficult) to edit the file-data anywhere else than in the files&images-tab, I guess I have to (1) follow you're route, (2) create a custom tab with datamodel and (3) in the mean time close the files&images-tab for all types of administrators.
