Ok folks, I know there's a way to go into my computer and change which photo viewer is the default viewer. Right now when I double click on a photo, it opens up in PhotoImpression 4. I have a newer version installed on my computer and would like the new PhotoImpression 5 to be the default photo viewer. I can not remember how I set it up to be PhotoImpression 4 in the first place and its frustrating me to no end! HELP!
