[Phpwm] possible?

'field' and 'image_id' refer to the id attributes of the input and the
image respectively (your page has 'text1'), and the function itself
attaches the onchange, so your HTML doesn't need to. You do need to
run it on window-load though:

window.onload=function() {
  $('text1').onchange=function() {
    $('image_id').title=this.value;
  }
}

where $=document.getElementById because I'm lazy and always typo it.
