This question has been answered a number of times recently, it probably belongs
in the FAQ.

IDL> plot, x, y, title = 'This is my plot'
IDL> image = tvrd()
IDL> write_gif, file, image ....

I believe this sequence works if you are on any windowing display (X, Windows,
Mac). For better speed and more flexibility, first issue the command
SET_PLOT, 'Z', /NOZ
to write to the Z-buffer pseudo-device. You can set its resolution, and its
write and readback performance is very fast.
