+	 *	Quota Display
+	 *
+	 *	Modify the following few elements to change the display of the image.
+	 *	Modifiable attributes are:
+	 *	bool	border	::	Defines whether you want to show a border around it or not.
+	 *	bool	unknown	::	Leave default; Defines whether quota is "unknown"
+	 *
+	 *	int		height	::	Defines height of the image
+	 *	int		width	::	Defines width of the image
+	 *	int		font	::	Changes the font size & font used in the GD library.
+	 *						Available values are from 1 to 5.
+	 *	int		padding	::	Changes the offset (in pixels) from the top of the image to
+	 *						where the top of the text will be aligned.  User greater than
+	 *						0 to ensure text is off the border.
+	 *	array	limit	::	Holds the integer values of in an associative array as to what
+	 *						defines the upper and lower levels for quota display.
+	 *						High - Quota is nearing capacity.
+	 *						Mid  - Quota is around the middle
+	 *						Low  - Currently not used.
+	 *	array	color	::	An associative array of strings of comma separated values (R,G,B)
+	 *						for use in color creation.  Define the RGB values you'd like to 
+	 *						use.  A list of colors (and their RGB values) can be found here:
