Changing a Window's Background to a Picture (in the script)

[bluelink91]

I'm using a mail client (found at http://www.creationasylum.net/index.php?showtopic=2549) and want to change the background of the message that pops up.
I think that you have to use something like:

@letter.bitmap = RPG::Cache.picture("Paper")

Where "letter" will become the background of the message window and "paper" will be the background image.
I've played around with the script, but still haven't found exactly what to do.
