I'll send this form email to people whose images don't show up in the Drupal Planet aggregator. At least until the root issue is solved.
I noticed that when I look at your blog posts in Drupal Planet, they're missing images. Check out the screenshot at http://justagwailo.com/junk/[image] for what I mean. That's because the Drupal aggregator doesn't resolve relative URLs to images and links to the originating domain. The open issue at http://drupal.org/node/88183 has a description of the problem. The short-term solution for now is to use absolute URLs for images and links, which isn't the greatest, but it means the hundreds of people viewing the post there get the full experience.
