Right, I didn't know. When we DisableMarkup('img'), the "http://www...jpg" 
thing is treated not as an image, but as a regular external link. But the 
MakeLink function re-checks it to see if it seems like an image, regardless 
of the markup rules.

You should also add to CommentPages.php this line :
  $ImgExtPattern = "$^";

This line will cause MakeLink to skip the "check image" part, and instead to 
display the link, like any other http://... link.

I just tested it here :
