my photos will not open on my canon power shot G10 after os upgrade

Hi Bishop-NewYork,

welcome to the Apple (user-to-user) Community

Re: my photos will not open on my Canon power shot G10 after upgrade on iOS.

Maybe try re-starting your device: iPhone or iPad (or Mac: Apple menu > Restart)

If things are not working right, restarting can often clear the way.
