Perhaps someone could go into this in a little more detail? I have
photoshop (Mac) at my disposal, as well as a UNIX box (that I am more

What do you mean by "Frame"? Do you mean save it (the random image) as a
postscript file at 150dpi, then scale that image by 50% and save as a gif?

What are the advantages to this?
