How To Draw Cartoons Free Software

I was wondering how to make a cartoon based on looking for a normal picture?
I've seen several people on MySpace with pictures like this where the color and everything looks different from what the pictures look as if they were drawn. Does anyone know how I can do this to my images? and if there is any free software that will help me do it? thanks so much
Microsoft Digital Image or other standard software for photo editing allows you to apply different "effects" an image as "ink", "pencil" or "pencil." Otherwise, you can do it the old fashioned way: pixel by pixel in the implementation brush. Just open and save your photo under a different name work anyway. You can find a free or free to try photo editing software license for download@www.download.com, even if you decide to use it only once and then remove the program from your computer.
