Ok, after you are done with your character, push the PRT SCR button. It is toward the top right of the keyboard.

Open up Paint and go to Edit then Paste.

Then you will have to crop the photo since it copied your whole screen. Click on the button in Paint that is on the top row and looks like a rectacngle made out of dashes. Select the area of the photo that you want with that tool. Then go to Edit and Cut.

Then you can go to File - New and once it opens, go to Edit then Paste again. That should bring up just the part that you selected and copied.

When you save it, be sure to save as jpeg instead of bmp so it will be small enough to post here as an attachment.
