Thanks for your reply. Unfortunately that doesn't solve my problem.
When I get the list of all that are deactivated I still have to edit each one to reactivate them which is quite time consuming. If I check the boxes for multiple images to reactivate several, the info about the images eaither disappears (if I don't fill in anything in the edit box) or all pictures get the same info.
I'd like to have a choice to check the boxes in front of the deactivated pictures and then just click on a new button that reactivates them all at the same time? Isn't that doable, please?
