image is the same as a submit, it will send off the form. You could 
circumvent that by adding return false to your  event handlers. However, 
to render the output as HTML you'd need to open and close  the document 
in the window. A better option is to read the value and set it as the 
innerHTML value of an element in the page, this also  means you need no 
popup!
