Thanks, Jamie. I think you're onto something here.

Facebook picks up based on one of two things:
Open Graph tags
Add a head meta tag <meta property="og:image" content="{IMG
URL}" />
(Easy solution is a regex to pick image out of $node->content
and use that. If no image is available, then have a general purpose one available to throw in the tag. This can all be done in the theme.)
Parsing Content
If there are no OG tags, then FB will try and determine the image
from the content. A lot depends on the HTML structure of the page. Sometimes you can reorder things in the template to get it to pick up.
For testing purposes, use the Facebook debugger:

Facebook only scrapes pages once every 24 hours, so using that
tool is the best way to make sure you got it.
