I don't agree this is a good solution. This form
  	plot "< convert pic.jpeg rgb:-" PLENTY OF OPTIONS with image

is really ugly and user unfriendly. I propose gnuplot reads png, gif and 
jpeg files directly using the GD library. This won't add any new code into 
gnuplot but it will make this feature portable to gnuplot for Windows, for 
OS/2, for Mac. The ImageMagick is usually installed on modern Linux systems, 
but I doubt for elsewhere.

Look at zimg, which can also read directly these files thanks to the GD 
library (right, Johannes?):
