Actually, not being able to run ASP (ie server is not running Windows) can be a very good thing. The GD library should be available on most versions of PHP, including 4.4.1. Run a script with the function call: <?php php_info(); ?> to see if GD is available and which version. Since this is likely a Linux server (since it is not Windows) another possibility is a series of command-line tools called ImageMagick which you can access with PHP using functions like exec(). This is not simple to do but it can be done if your host will allow both ImageMagick and exec() functions -- many do not because both could be abused. As you will see on http://php.net/ version 4 is reaching the end of its maintenance life. You may want to shift to a host which will keep up with the security updates and versions. Are you trying to change the color which is showing through the transparent sections? What type of images are these? PNG (IE is not always good with PNG transparency), GIF (some versions of GD can't or won't touch GIF files). Depending on what you are trying to achieve, there may be another way to accomplish it. Some more details and a sample link to an image and what you want to see would help us help you. James
