Kim, I think we found out why it is doing that.
Here is what Dave said. " It happens when the user is using the Chrome browser with a certain add-on that causes this. I don't remember which add-on it is, though. It could be a malware that is causing it. The software is adding that code to her posts when she makes the post. It's not something I can control, unfortunately."
But don't work if you can't get it figured out. I am loving all of your photos.
