I tried to share them by creating a post on my FB page and then clicking on the pics I want from the folder that opens. What's weird is that only one of the pics that I took shows up, even though they're all there when I open Photos. I get what you're talking about and it looks like that could work, although I'm not sure if I could share them to the original post I made or would have to create a new one.
OK, I tried to share to FB, but it isn't one of the options that comes up. It's more like email, texting, and such.
