I'm crawling my way towards this.  What do you think of this construction
(Hamapatch creation) as a sufficiently believable body joint?  I think I
could almost figure out how to code this if I keep things simple like the
hamapatch joint at the inset.

It's also disturbing to me that the render window for this image showed a
much brighter and vivid blue than I saw when I loaded it up in a paint
program.  Any ideas on what could be going on here?

Me neither.
For me that is probably because it is uuencoded
end my news reader (netscale 7.1) does not support
that for reasons beyond me. Perhaps I should
instal a plugin or something. I have this problem
too often when using these newsgroups. Anyone some
suggestions?

BTW I know it is UUendoded because I saved the
message as a text file and looked into it.
Then after changing the extension from .eml to .uue
my winzip recognized the embedded image and I
could open it in PSP.

That's what I'm obtain :

The image "fourknee02.jpg" cannot be displayed, because it contains errors.

Normaly, Netscape, Mozilla and Mozilla Thunderbird support UUencode 
natively. I was able to view the image using an external app 
(IrfanView). I don't know why it refused to display that image, while 
displaying all other UUencoded ones...

Well, the message looks OK to me, except it doesn't decode into a proper 
image.

Usually what happens is someone posts a uuencoded body inside a message 
tagged as content-type:text/plain, and your news reader (being standards 
compilent) says "Oh, plain text, the sender says so even tho it looks 
like it might actually be a uuencoded message."

FWIW.

Hmm, xnview identifies this file as "JPEG CMYK (v1.1)"  as opposed to
JPEG Truecolor (v1.x). And does appear display it correctly.

Yes, its CMYK instead of RGB. This is the reason why the blue gets darker:
the CMYK color space is smaller than RGB, and bright RGB blue can only be
converted to a darker greyish CMYK
blue.

I am not sure about that. My browser displays it as a broken image.
So it knows it is an image.

Ok, I looked into the message file again. There are no mime headers
at all. Could this be the problem? And if so, why do I get a broken
image image.

Confused,

That's why I said "it looks like just a broken image to me", and 
"Usually what happens is..." in response to "this happens frequently to me."

I wasn't in this post addressing specifically only this particular 
broken image.
