Paste Render
From GECK
The Paste Render command works similarly to most other Paste commands. With the Render Window highlighted, select a cell you wish to put your previously cut or copied render and simply select Paste Render from the Edit menu. The render will generally be pasted directly in front of your P.O.V. (point of view) in the Render Window. You're now free to move the render into place you want within the cell. You can paste the cut or copied render as many times as need be.
