Sometimes I upload a bunch of images to a gallery and then realize they all need to be replaced. It seems that I have to click each box to delete all the images in a range. It would be much handier if the normal shift-click (and control-click) mechanisms for extending (editing) a selection worked -- that is, I'd just have to click on the first image and shift-click on the last, and they'd all be selected.
Is that doable?
