png or jpg manipulation in php

[oldmanstan]

anyone know of any other ways to manipulate (resize mainly) png or jpg files using php preferably but perl would probably work too? i know the GD library in php allows this but it is not available to me for this project.

Neat trick I just learned: sizing imgs with ems in CSS.

I dunno if this helps you, but anyway it's cool. :)
