generally it's ok for web use, particularly with downscaling. i have noticed degradation recently on png images though.

the appropriate functions are imagecreatetruecolor and imagecopyresampled. the manual is excellent on both and there are lots of sample code snips in this forum too. there is also a gallery script i wrote that has the functionality within it. found at

the source code is available through clicking the link button at the bottom.
