So here's what I'd like. My front page has the opportunity to drop in something that's 480 pixels wide, and one opportunity to use this would be a random photo display that would call a featured photo from posts--plus its caption--and would have a link back to the post it came from.
The objective, of course, would be to pull users to older posts, teasing them with pictures.
You can see what I'm talking about at http://www.carbuzzard.com
I've looked and couldn't find anything like this, but maybe that's because I'm not using the correct terminology.
