	Original Mash Up By: diginc aka injate on 03-07-2006
		Basically I just combined two scripts with some minor mods
		
	The original purpose of this is a signature that acts like a normal image when there are no recently played tracks.  So it just shows the tracks and nothing else on top of a background image.  The spacing is dynamic to match the size of multiple images.  Minimum image size for 10 tracks: height x width 137 x 375.  Remember to use a font color will display on your image well.
