Since nowadays this excellent module is used for more and more intricate
implementations with the ability of all kinds of field definitions, it would be
very very nice to have the ability to update an already uploaded image with a
new version. Now you'd have to upload it as a new image and copy paste
tilte/comments and all the extra fields manually to accomplish this. Since the
editimage action already is able to edit the image it would be nice to also be
able to upload a newer version of that image there.
