Ok this is officially a big bug. When I go to edit either of your posts, I see nothing - no link, no image, nothing. When I click on your link, the site prompts me to relog in - even though I am already logged in. However when I DO log back in, I can see the image just fine, and I can now go back to your posts, edit them as the admin, and see the image.
So right now when I edit your post, I see the image of the grow box in my edit window. But when I save changes and go back to the site, I see an image icon with a big red "X" over it.
Bugtastic!
