Not that this has much to do with Perl in particular, but...

You can do something like the following:

<form method='post' action='http:/whatever.com/foo'> Address: <input type='text' name='address'> ... <input type='image' name='whatever' src='url-to-image.jpg' border=0> </form>
Or if that does not do what you want, you will have to do Javascripty things:
<form name='form_name' method='post' action='http:/whatever.com/foo'> Address: <input type='text' name='address'> ... <img src='url-to-image.jpg' onClick='document.form_name.submit()'> </form>
You can do the same kind of thing with simple link () tags too. But people need to have Javascript enabled.
