Create a GUI to Manage Shared Images
There is currently no way to review image in the Gallery. It would be nice to have the mean to review, edit, delete the gallery.

Looks like this idea has already been done. You can manage images in the gallery by right clicking on them. You then have the option to Rename, Delete or Replace them.
It's fairly basic and it's a shame you have to go into design view on a form or report to get access the the Gallery, but the basic functionality is there.
