(adsbygoogle = window.adsbygoogle || []).push({}); Ok, well not everyone has photoshop, so I'm just going to show you an amazing website. It's an online image/paint editor, no download required, no signup and you can save the image you created straight to your computer. It's got everything in it, bluring to texturing, shadowing, gradient and hundreds of different paint tools. You must login or register to view this content.
Just click open Sumo Paint and have fun

Otherwise there is The Gimp, way better!!
