From The Pink Floyd Encyclopedia:

Cover art: An out of focus film still of a man in a tree. The man appears to be striving to reach a goal, while the blurred points of light are reminiscent of early Pink Floyd light shows.
The 1996 remastered CD uses infra red landscapes, as suggested by Jon Crossland, and produced by Angus MacRae.
