how can anyone like or comment my picture without being friends on facebook?

[Ryan]

i've been trying to figure out how people who aren't my friend on facebook can like or comment my picture on facebook without being friends, it is possible because I've seen people with it, and I tried setting everything to public but that didn't work! Help!
What do I do in privacy settings? i've looked everywhere.

go to "privacy settings", it's an issue with your privacy settings

Make your privacy to everyone. But they only like and comment on your update but not on photos. You most have friends to make comment on photos.
