Watermarks
It is possible to add a "watermark" to a plot. Simply load
in an image file in the watermark panel and set its transparent colour
and overall transparency. 
It will be drawn in front of the normal image, using the transparency settings you have defined. The position and size can also be set.
Below is an example with black as the transparent colour (the image was created on a black background) with 20% opaqueness.
