And when you create the images one time, it's done ZERO times.

And no, the data isn't always taken from some kind of cache.  It depends 
on a lot of things.  For instance, a PHP script is compiled every time 
it's called unless the server can determine nothing has changed 
(generally not the case) or you have installed additional PHP caching 
software.  Web servers do not cache compiled code, and neither does the 
PHP module by itself.

Back to the subject at hand - every time the system has to handle a 404 
there is wasted time.  And it is a relatively significant amount of 
time.  Adding the necessity of resizing an image to that can be costly 
on a busy server.

Of course, if all you get are 200 hits/day, it doesn't make any 
difference how you code your scripts.
