This picture is a JPG. I did like this:
Using 1024 x 1024 bmp skin setting in AH and work on the same size in Photoshop.
Using screen resolution of 1600 x 1200.
1) made a screenshot in AH (Alt-s)
2) made a cut in MS paint
3) pasted that Image into Photoshop with 150dpi
4) saved as JPG in a compression size 10
