Out of the box easy, and while I'm not using it in the traditional sense, I may incorporate it as a gallery as well at some point.
I would only like to see the "alt" tag filled in as well like it does with the caption, with an option to not show caption. (I realize I can delete it, but if it's going to be easy, it should be easier) :)
Google is looking for those alt tags tho, so it would be nice to see this get auto filled in as well.
Thanks so much
