Thank you Wayne, Richard. I didn't know about the part where information
can be saved as a text file. Definitely helpful. And thank you for the
additional detail Richard, it seems I'll have to create macros because I do
have a lot of images.

Yes Jim, I'd been starting to ponder that approach myself. However, I think
I'll first give a try to the raw images and text files, since information
in the text files can be read using any text editor unlike that of the .hdr
file. But, thank you for the input.
