Idea to overcome image posting problems

At the moment we have a default image feature is is great.

But rather then use the same image for each post it would be good to be able to upload say ten images for each feed and these could be rotated through so each post from that feed got a different image.

Better still would be the ability to use a specific gallery for each feed again rotated through for the same effect.

Galleries could of course be shared so a slight tweak on that would be for the plugin to monitor which image was used last in a gallery and assign the next one in that gallery so avoiding the same image being used to quickly.
