Thanks, Al.  I was looking at your programs in the archive and I saw the jpeg
decompressor although I haven't checked it out yet.  I will do so.

I'm interested in compression techniques but without the advanced math
background I sometimes have a difficult time understanding it.

Thanks again!

BTW, what does your tagline "I brake for LED's" mean?  Are you a hardware guy? 
I'm an electronics tech by profession myself.
