Hmm, I don't know. I just opened the picture and copied and pasted the url here. I'll see what I can figure out.

Edited to add: I don't see anything on Picasa about BB code or any way to link other than through Google+, but I'm fairly sure I've seen photos here that others have shared through Picasa. I have to say that posting photos here is very frustrating to me, which is why I don't ever have them in my trip reports. Obviously others don't have that same problem.

Edited again to add: I just copied and pasted the link and it went right to the photo. I wonder if it has something to do with the fact that I'm logged into my Picasa account. But regardless, I thought if we used the image tag that TTOL provides, that would show the photo in the post itself, and not rely on someone having to click on a link, or worse, having to copy and paste it into my browser.
