Day Two of new course

I am trying to do this for the second time. By this time next Thursday I hope that I can show my husband and son how to blog, insert an image, and even copy a video into this "thing." Wish me luck. You'll see the results of my efforts...I tried insert a beautiful image and do you see it here? I don't. This then disappeared when I clicked on the arrow back. I can't believe I found this again-when I scrolled down to click save now I saw "return to list of posts." It worked! I found it! I think I'll try the image again. Once again, blank. Dennis tried to help me but we'll have to try that next Thursday. I don't even want to try a video today.
