In Closing

As with any development project, everyone has their opinion of the best package to use. I have been very satisfied with the gd C library and the interface for creating GIF images on the fly. You may find other packages or interfaces that suit your needs better depending on your experience and your web server platform.

My only advice comes originally from my Dad, but slightly modified for the nineties and GIF image creation: “Never use a wrench (image editor) when an air ratchet (programming with can do the job.”
