Image resizing...

Hi All I've been working on finishing a project SGML2IMAGE and I am sort of having trouble with resizing of images. I am trying to just use the GD library so when I distro the package it will not need any other things installed to be used. Now I am using... imagecreatetruecolor (); imagecreatefrom___ (); imagecopyresampled (); image___ (); But the thumbnails look blurry for any image less than 50% of the original image created by the PHP SGML parser. So my question seeing I am not very good with the GD library. Am I using the best functions to do the resize or should I be using some other image function(s) that may give better results! To give you a idea of what I am doing see the demo running on my note book.... http://24.218.192.217/capture.php Thanks.... sonia
