f**** outlook web app

outlook web email doesn't render images inline,
even though claws-mail (using libwebkit) does (at all different
permutations of my html code).
I've tried to make the code as valid as possible, although python
seems to change all my closing tags back to normal ones (strips '/')
keeping the document invalid.

but either way I've seen way more invalid documents rendering with
images in outlook. so i give up.
