Image
This data field is displayed as an image. If there is no formatter, the
		data value is assumed to be the URL of the image, and thus the image types
		supported are those of the browser. If there is a formatter, the image must be
		handled by the portal. The supported image types in this case are: BMP, GIF,
		EXIG, JPG, PNG and TIFF. See also 
		http://msdn.microsoft.com/en-us/library/system.drawing.bitmap(v=VS.90).aspx.
		
	 
If you select the Image category, IPFImage and SLImage are listed in the Formatter field.
