I dont like my users the turn of my predefined settings nor I donbt like them to switch off my theme (because of banners etc), others may want to allow it so I think it should be definable in the admin menu whether to allow it.

I get your point. The idea came from CNN's galleries - see for instance www.cnn.com :: war zone :: Gallery.

Using an admin setting could be one way to fix it - but we could also use the permision system which would allow the site admin to give "remove frame" access to specific users.

That (the permission system) would probably be the best idea, I think. yes ;-)
