"I found that you have to change the settings for the size of picture. I guess the last picture was too big? I will try again with posting this as the original size. What do ya think?"
Good enough, but the picture is not quite centered. I think that indicates that the original size is a skiff too big. I changed it to the "Large" size, and it centers. Users can always click for the original anyway.
You could try editing the size of the original image, but we probably don't want to get into that. ;)
