I haven't to complete trick of it, but you use the flat square (terminology will be vague), and make it large enough to be a backdrop. Then go into the part with the 4-armed man (from Da Vinci), and create a jpeg, and use it as a texture for this.

What always gets me is the dimensions of each. If you get the jpeg too small, you get pixillation when applied to the square.
