I'm glad you tried it because I've always wanted to see if my Google photos or drive images would view publicly. Maybe put them on your Google+ page and then link from there?
Haven't had time to check it out yet. Don't have any aspirations to use google+ or any other social network, but I will attempt to find a solution when time allows. I assume that y'all have confirmed what Chris has said? You can see it if you're logged in to gmail?
Me either, I have a facebook account and hardly keep up with that. Actually I originally tried Google Groups, then I tried buzz and ended up just using facebook. I like the idea of Google+ but I'm afraid its just another social networking tool that will fail. I'm always logged into gmail and I still can't see them. I think only you can see them because you are logged into your gmail account.
