I don't actually know. These are 256 color images produced by the Navy and
posted every 12 hours. They show sea surface temperature anomalies -
variations from an average temp I guess. I want to be able to compare each
image to the previous image to show areas of temp. change for the given
period.
And it's easy in Photoshop to subtract but I'm doing it in Director so it's
not quite as easy but still shouldn't be hard...
I think based on the size of the list I am just going to do the processing
as requested and not try and store it as I go...
