send pics over slow line?

[Dave Stevens]

Hello All,

I'd like to send a lot of jpegs across a modest bandwidth line without  
using up a lot of its available capacity. The images are sequential  
snaps of a landscape where there is very little change from one frame  
to the next. I'd like ideally to send the first frame in each hour  
then subsequently send only the frame-to-frame diffs, which ought to  
be small.

I'm sure this is a solved problem somewhere but I can't see it.  
Certainly zipping or gzipping don't work in any obvious way (or not  
obvious enough, anyway!) Suggestions?

Dave

life in the United States.
