Sometimes scanners just make our lives difficult. They have silly defaults and, sometimes, no way to change them. I’ve heard of one scanner that always scans the same size regardless of what you tell it. Its view is, “you can fix that in software.”
I’ve heard of another where it always scans upside down. Probably there is a feeder or it’s installed somewhere where you can’t insert the paper any other way.
So, for the times where it really shouldn’t be this difficult, I’ve added a program to the GssEziSoft collection called FixPic. It will turn pictures around or flip them over if you need it to.
You could also use it to update a batch of pictures (if you have a stack of old sideways scans, or something like that).
