You may want to look into using the imagecopyresampled function if you 
are running GD 2.0.1 or later.

I would also recommend investigating ImageMagick, as I've had very good 
luck with it in the past. (Personally I like to use the "montage" 
program it provides for doing image resizing and thumbnails.)
