[imp] IMP 4.3.3 can't handle large jpg attachments

[Scott Toderash]

FYI, for the list's benefit
solved (sort of)

I installed ImageMagick and did a few things and rebooted the server and 
the problem has gone away.

My assumption is that in the absence of imageMagick, IMP does some JPG 
processing in PHP that is inefficient, and doesn't scale to images that 
are 200k or so.  Interestingly, I made the changes, restarted httpd and 
saw no difference.  I ended up rebooting the machine for different 
reasons, but afterward the problem had gone away.  I can't prove for 
sure what the fix was, but it's done.
