This is a simple picture generator. You can create several styles of images. Each small icon below represents the style of image that you can create if you click on that icon. For example, lets take the first 4 icons. I class those as marble effects.
You can use the generated images in any way you see fit. This is a free to use tool. I mostly create things like buttons for my games using this generator. It saves drawing by hand. Each image created is a jpeg file. I know its not the most amazing whizz bang image generator you have ever seen, but it is simple to use.
