[Geotiff] Transferring GeoTiff tags

[mrl]

Ned,

We used to do this all of the time at ImageLinks.  Just another note,  
my son David tells me that there is a developers kit for Photoshop  
which provides both Applescript and Javascript interfaces to Photoshop  
functionality.  They were able to use this to automate stripping the  
tags (see Frank's comments below), stretching imagery and feathering  
boundaries, then output and retagging.  They then can automate  
directories of files through this process.
