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.

Ok. My point was that it didn't explain the problem in this
post. His new post is ok, yet it still does lack mime headers.
My guess at this point is that the uuencoding was not the
problem, but, as somebody else discovered, that it is a
CMYK image. Probably then my browser can not handle that
while my PSP can.

With Knode and RedHat 7.3 I don't have any problem...
