I can help here. So you HAVE a PB account, and pictures uploaded to it?
Click on the picture you want to use. You should see a box open that says "share this image" with four options (html code etc.) Copy the entire line in the option labeled "Direct Link".
Come back here, and click on the Insert Image icon in your post. It's the one that looks like a yellow square with a mountain and a sun (moon?) lol round thing. Clicking there will open a popup window. Paste the copied info from PB into that window, and hit ok. The picture should now be in your post
You won't actually see it until you post it, or preview it though, until then it will just look like code
Ha. THat pic is just for funsies, I used it as a "test" run to make sure this worked.
