No, that won't do anything. Input type="hidden" is set as display:none. All that the above does is apply a pointer to the <u>.
You want to get rid of the image? Remove that input. You want to click 'pointer summary' to submit it? Turn pointer summary into '<input type="submit" value="Summary" />' and style it with CSS to remove the button features if you so wish.
Don't ever think 'How can I modify what I have to make this work', think 'How would I make this from scratch to make it work', and then think 'How can I modify what I have to do just that'.
