I didn't see any headers I didn't know about. Which header are you 
talking about, that my mail client wouldn't know?

So what's executable about a jpeg file?

Fine.

Yes, and that's why HTTP uses them too, right? ;-)

If this is the case, then you shouldn't be putting MIME headers in news 
posts. But of course this will be a go-around.

Sure. And if web clients showed you broken content instead of silently 
trying to correct it, a system like Google wouldn't have to incorporate 
every known trick just to work, because the first time the designer 
looked at it they'd see it's broken.

Note, btw, that the guy who said "be generous in what you accept" later 
said "oops, that doesn't work too well."  ;-)

I haven't looked at the web view. Does it allow for mixed text and 
images?  If so, then yes, you need to do a bit more work. Not a lot, but 
a bit. I'm happy to help answer questions if I can, as I've done this 
sort of thing myself way too much.
