PHP / GD Library problems

[egodshall]

Does anyone else have problems with the GD library for PHP? I have 2 scripts that use theses libraries but none of the generated images are ever displayed... I have checked php_info() and it looks like everything is enabled.

Thoughts?

How large are the images? I've had problems with GD where I'd load the images into memory, but would surpass the memory limit.
