Jep, haven't cut them down into small pieces yet. Send me a link to the
images, I'll add them.

jep, thats a very interesting idea. I haven't tried anything in that area
yet, but probably we need a bit more than just scale the brightness values
by a function of the exif data, but the general idea is great.

Yep, most important right now.

looks very good. unfortunately, I can't see the flash panoramas right now
