I don't know if it's really a bug.
But if you use IMG tags as a link to another URL or picture (like the imageshack thumbs in this post: http://lfsforum.net/showpost.php?p=15262&postcount=11 )
and you have the "Show IMG tags" option in you profile disabled, you just see a link to the thumbnail, but not the link to the real image.
Which means you could never use such links, because you'll never know if someone enabled or disabled it.
I hope you understand the problem
