OT - Having a problem displaying image thumbnails

Cameras can do all kinds of things with image data, but I can't think of any
software that'd honor a "do not resize this image" setting even if it were
set.

Find out what the problem is by doing "identify -verbose NON_THUMB.jpg >
nonthumb.txt ; identify -verbose THUMB.jpg > thumb.txt" and then looking at
the first hundred lines of output in both files.  Then play "one of these
things is not like the other".  The problem should become obvious.

A while back, someone sent us a JPEG at work.  This image would render just
fine in Safari and Firefox, but wouldn't display anything in IE.  The problem?
 Its color profile was CMYK, not RGB.  *sigh*.  Your problem may be similar. 
HTH,
