Trying to Add an Image to my post

I'm trying to add an image from my computer to my blog since I have been unable to move my pictures into my Prezi. I clicked on add an image, selected my picture, and clicked back to edit my post and voila...no image. This too falls into the category of "challenges" in Cs of Becoming Tech Savvy. This certainly has been an evening of challenges. Read my next post for the continuing saga of Challenges in Entering the Promised Land of Tech Savviness. Before publishing this post, I will try adding an image one more time. Here goes..Well, my picture was successfully uploaded to a blog post, but when I clicked "done", this is what my post looked like. What is all the gibberish at the top of my post? Help? I was so excited when I saw the image uploaded in my post box. And the instructions said I could edit and post. I will post it as it ended up and perhaps someone can explain what happened to my picture.
