(1) Choose File: I uploaded my file that contains "my two dogs 2013.jpg." Now, I am not sure if it is the right picture. How can I see the picture before I submit it? Can you explain me how to create a small image box next to the filename on the right side? Let's say 1" x 1"
i.e. All I can see my filename attachment, but no picture. Let's imagine that it is a wrong picture with a correct filename of someone who is naked and you wouldn't want that happen. Who knows.

(2) I was disappointed to learn that many people have no idea how to upload their image on their computer. Most people took the pictures and saved the files on their computer. That's it. Some people know how to attach it on their e-mail. But, not on the web form. How can we explain to the people on our web form - step by step?
