I tweaked my original design of the Marvel Heroic character sheet and added an option to embed a picture into the PDF. The picture itself should be on a 1:1 size ratio (ie, 400×400 pixels, 5″x5″, etc). This is best viewed with Adobe Reader.
If you just want a square white space to draw your own picture, instead of embedding a picture of your own, just don’t add the picture and the space will remain white.
