Have you tried to colour it in yet? Click the button that says ColorMeIn below your picture, then change some colours and the save and post the new image. It should now apprear below the original in the 'recent versions' bar.
You edited the original picture. I looked through your gallery. I assume it is this one: viewtopic.php?t=747058 You edited the picture with the order instead of using the "Color Me In" button.
