Hetty, do you have to do the "Discard Changes" step before you save? I did find it on the Edit menu, but it was grayed-out, not an option. I still have the original picture on the camera card, so it isn't entirely lost, but thought it would be nifty if I could restore the accidentally saved one.
Woofie, yes, a jpeg.
Dave, I have a feeling you are about to get a whole lotta banner submissions!
