problem generating PNG using image functions

Hello,

I have some php code that I moved from one serve to another.
The code in question generates some PNG images on the fly
and works nicely on the old server.
After moving the code to the new server only one
of the PNG images now draws. The other images
come back with :

The image "http://url" cannot be displayed, because it contains errors.

Why would php generate one image but not the others?
(keep in mind that the code is known to work fine on another server)
