Here's another random image:
A near-terminator shot. Again I didn't check its location. These are 32-bit images, but all the action is in the lower 16 bits, so as a tip for people who want a quick way to browse them: import as a Photoshop raw, using 16 bit IBM format and either 1024 by 548 or 512 by 548 as the size (depending on the file size). That splits each 32 bit pixel into two, making vertical lines down the image, alternating between image and blank. Now use 'image size' and nearest neighbor sampling (will not work otherwise!) to reduce to 512 by 548 or 256 by 548 (depending on file size). Now you have just the image lines left, and a contrast stretch will optimize it for viewing. After a good stretch it can be saved in 8 bit if you prefer, as this has been.

Phil, that sounds like a rather un-quick way to browse images! Wouldn't a faster method be to just dump an image properly into a PNG?

True! Obviously IMG2PNG would be better than the approach I described. I just wanted to offer a method to people who don't have, or don't want to get into, that software.
I doubt if I will ever do very much with these images. Sadly, their time may have passed already. Phil -------------------- ... because the Solar System ain't gonna map itself.
