Delete Photos

Hi Sebastian,
thanks for the plug-in.
I have a question / problem though: How can I delete a photo from the tab? We have a situation at the moment where the tab shows photos that do not belong there, but we have no tool to remove them. The photos need to stay in the media database though for other purposes. So it’s not an option to just delete them centrally.
Thanks a bunch, Chris
