Yes. In Flack, if you click on the blue (I) in the node box, you will get a
screen, and on that screen is a button to create an image. Click that
button and fill in a name for your image. Be sure to remember that name,
and reuse it the next time you create an experiment. You will see that in
same screen, a place to specify the image to use.
