To read and write jpegs, you need to install the jpeg library and compile jpeg support into GD. Then compile PHP to use GD.

The same for png.

Or ... you can go and compile the beta 2.0 version of GDlib, which comes with a leetish jpeg, png and bmp support. however ... the Gif format is traded out and not supported at all.

I've been using 2.0 for quite a while, only bug I've noticed is an alpha channel bug when merging a PNG image with a JPEG image (to stick a logo on the image ...).
