Should I be worried about eye cancer in my daughter?

I was taking pictures off my camera from Christmas for my mom, and in one picture I noticed something about the reflection in my daughter's eye. There was red eye in one of her eyes, and the other one had some red eye, but some of the pupil looked white. My husband thinks its just a bright light that flashed from somewhere else when I was taking the picture. But am worried about it being cancer. Should I be worried if it is only in one picture. She has red eye in both eyes in other pictures, just one pictures has the white on her eye like that.

She is 20 months old.
