Image only works when GD is installed

You also (obviously) have to tell php to compile using gd.
Take a look at any phpinfo(); page and see if gd shows up anywhere. If it's properly installed, it will.
Keep in mind, also, that you don't HAVE to use the "image" format, you can use javascript, or html, though image is one of the better options.
