As Christoph M. Becker has already posted, input of type="image" is not 
included in HTMLFormElement.elements [1]. So, you'll have to add these 
inputs in your code. For instance:

function serialiseForm(frm) {
   return [].map.call([...frm.elements,
     ...frm.querySelectorAll("input[type=image]")],
     el => ({type:el.type /*, ...*/}));
}
