Attached images in HTML preview section do not render. Here is an example:

Image kinda big

The images' src is always a non-URL. For example:

cid:37686D32@F0369F32.19717862.jpg

A fix for this issue is to rewrite the image tag's src in the HTML preview section. cid:37686D32@F0369F32.19717862.jpg would become http://example.com/api.php?a=attachment&email=test@example.com&id=12345&filename=test.jpg.

Also, < and > is getting rendered inside the Raw Email section as HTML. These characters need to be escaped.
