Suggestion: Story thumbnails

This is (yet another) suggestion for GL 2. It would be cool if in story submission when you have the list of images to add if you could check a box next to images that you wish to be thumbnails.

What I mean is that when you enter \"[image1]\" in your story, if you have checked the \"Thumbnail\" box next to image 1 in the list then it would would be clickable and show the full-sized version. And on the full-sized version, there would be an automatic link back to the story page.

I know this is all do-able manually, but I think it could be coded fairly smoothly. Did that description make sense? :)

Maybe it could even tie into Gallery? Maybe not...
