I agree with much of the rest of this comment.  Apache is great at
serving files, so why not let it serve the images directly.

this should be " instead of ' by the way.


You can have perl include an 'expires' header for your CGI output, and
then browsers will cache it.  

	print header( -expires => +1d );

sets the result to be valid for 1 day, so browsers shouldn't re-check
the file until tomorrow.  Do a 'perldoc CGI' and look for the -expires
option.  You can specify dates/times in many different formats.
