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

[Scott Toderash]

I recently moved my Horde/IMP installation to a new webserver with a 
newer Apache/PHP (now httpd-2.2.11/php-5.2.8). Since then I've noticed 
that JPG attachments cause problems unless they are quite small.  One 
that is < 100k is fine, but a 300k JPG causes the web page to time out 
when trying to view it.

afaik this problem did not exist on the old server but I can't say 
because it's dead now.

There are a bunch of similar problem threads back in 2005, but that 
issue was/should be long solved.  There was a patch posted that I tried, 
but no avail.  Same thing.

I Originally had Horde 3.1.5/IMP h3-4.1.5.  I installed Horde 3.3.3 and 
IMP 4.3.3 but same problem.  The problem also exists in DIMP h3-1.1.1.

The problem is specific to images, not larger attachments in general. 
For example an XCF (Gimp) file does not have the same problem.

I've tried tuning PHP/PEAR/PECL to see if I am missing some optimal 
libraries, but I have not been able to solve this problem.

Any suggestions will be appreciated.  I'm not sure what to try next.
