I want the groups to have just a little more editing power for the owners so they could put their own pictures (from paint) to the front or any other page. This would make me happy, because then I get to put my Kirby in my front page :3
Technically, you can already do this. If you have the image URL (which you can get via My Zone > Manage > My Gallery > Clicking on the desired image > Look at the address bar), then you can slap it in an [image] tag.
