Yes, plug the Image Map node into the Diffuse_Color channel. Once there, you should see the image applied in that preview sphere. To adjust the size of the square, go to the Pose Room. I find the Main Camera my best friend for this situation. Select the square, and open your Parameter Dials from the Window menu (if it isn't up already.) Once you have the dials, adjust the X and Y Scale dials to increase the size. (You are going to want to either manually adjust the Y Tran dial to bring the square back to the right level (instead of dropping through the ground.) I haven't tried just Drop To Floor, but I assume that should work too. At some point, the square should fill your full preview window. When you get to that point, you probably won't see your figure anymore. No problem, just adjust the Z Trans dial to move it behind you. That's it! Instant background. My opinion is this is a better solution than just using the background color. You get much more control over your background. One thing to keep in mind. If you cast shadows they will cast on this background like a wall. Another thing to keep in mind, if you use depth of field, you will need to keep that in mind as well. What I do is place the center point of my distance guide just into the background itself. If you do not know where to find it, it is at: Display-->Guides-->Focus Distance Guide. Hope this helps!
