I have to do a lot of gradient generating for the current project I am making and have found several tools online that worked, but none quite as simple as I want. What I WANT is a gradient generator that'll create CSS for the browsers that support it - Firefox > 3.6, Safari, Chrome, and IE, and then for those browsers that do not yet support CSS gradients, to create gradient images. So far I have the easy part, the CSS generation, working. Now to create the images.
