Onebox all the links!

May I ask a question? Let me see if I can word this…

My question is about copyright. I understand that one can post a small bit of something without violating copyright, right? So I assume that the oneboxes here don’t violate copyright.

Just now I posted this link: https://goo.gl/images/24ZqEi in another thread [here, if anyone is wondering]. I actually wanted to post a link to only the largest photo that you’ll see if you click that google link. But it didn’t want to just stay as a link–it would have posted the actual photo. BUT I didn’t know if I had the right to post the photo on the bbs! Any advice?

(Having the photo rather than just posting the link would have been more dramatic and would have made my point better, but again, I didn’t know if I had the right to do that.)
