Cindy, don't feel bad, you are not alone. I read through the instructions and none of it applied to my computer/settings.
What I wound up doing was going to the bottom of the screen and click on "Manage Attachments." I had to upload one picture at at time, but the post had them all run one after another. I made all my comments at the top of the post. Make sure you "preview post" before you post it.
