Posting pics was hard for me also. I finally got one posted, but don't know how or what I did to post it. My Son-in-Law posted one, and it looked simple.
I think when I go to post again, I will do better, and think this is where I fell down; going to where the picture is located in your computer. Find it ahead of time, so it is more easily found to post. It sounds simple, but that is what I think I need to do better to post.
Good luck.
