how to remove pictures from my ipad without removing them from dropbox
I think I am incredibly dumb, but I cannot figure out how to delete my pictures and videos from my ipad... but not simultaneously delete them from dropbox. The only things I can think of are....(option 1)... to copy the files directly to my computer (windows pc) with the box checked " delete the files on the ipad once copied" ... but will that delete the pics in dropbox? Or.... (option 2)... if i un-link my ipad from dropbox ... then delete the physical pictures from the ipad.... then re-link the ipad to dropbox....will it then go about deleting the pictures from dropbox or am i golden ..... please help !
iPad 2, iOS 7.0.4
