After you make the image, you need to hit the "Print Screen" button. Then open "Paint" (or another program like it) and click paste.Then shrink the botom right corner of the image to the picture of your character. Then rotate the image 180 degrees and do the same thing again. Rotate the image a final time and it should be right side up. Now save the file (in whatever format you want, preferably .jpg) and come to you post. You can either click on the "insert image" button at the top of the screen, or you can scroll down to "manage attatchements" and add it in that way.
Hope this helps, man these little guys are great, I wanna see more!
