Thanks, Richard. I'm already using that -- that's how I'm getting the
EXIF data -- but it's read-only, there's no way to take its data and write
to another JPEG file.

Yeah, that's what it looks like to me. I tried
im0.app = im.app
where im is the source image amd im0 is my destination image; that adds
the appropriate EXIF data to the PIL Image object, but it doesn't get
written out to the file when I do an im0.save().
This is still helpful information, though. I had no idea that PIL
supported EXIF, and I'd rather use PIL's support than load in Gene Cash's
module: one less dependancy.

Thanks. I think I'll go with JHead. This program is mostly for personal
use, but I may have one or two friends who may find it useful, too. I can
put in a "Preserve EXIF (requires JHEAD)" checkbox, so that it's useful
w/o it. It's probably easier to copy JHead along with my program than it
is to patch PIL.
Thanks to all responses.
