I'd also love to see more input on this topic. I have a Flikr account but am still confused about which images are OK. I haven't logged in for a while, so I can't provide specifics. For now, I'm using my own pictures and a few freebies that I've found in MicroSoft clipart etc. My question is, when I share a blog post to Facebook, my post pic isn't always shared as well. A lot of times, FB chooses my header to display. What's up with that? If the pic is mine and on my computer, it seems to stick. Otherwise, no. Help, please!
