So I'm working with the new version of WordPress 2.5 and the media library. Two things I notice.
(1) I can't seem to delete images I no longer want. The button is there but it doesn't actually delete anything.
(2) There doesn't seem to be a way to replace an image in the media library. Say I want to replace an old image with a better newer one, but do it globally and to all existing instances. Can't be done?
