GD image quality

I read Ben's article about PHP and GD and resizing images to thumbnail size, but I'm having a bit of problem. I got the image to resize, since I'm resizing twice. I first resize it from the original to a smaller size and then I again resize it from the original to a thumbnail size. I save it into the proper folders and set the quality to 100 and the result isn't so pretty. Any ideas on how to improve the quality?

I've never been able to get thumbs of decent quality out of the GD functions. Hopefully something better will come along =( You can try setting up a loop to resize 10% (of the original size) each time through until it's a thumbnail, that may help.
