Hi Randy,

This article will probably help:


I followed the link above. I tried to do Method B, everything to seemed to work, but every time I try to optimize, the program crashes at about 99%.

Then I tried method A, but there isn’t an “Altitude” column, under Image Properties Editor. I there a way to turn on additional columns?

Hello Clinton,

The altitude column should be there, would you send me a screenshot of your image properties editor?

Thank you very much.
