The form helper does not handle this functionality. The form helper
merely creates the input fields in the HTML and pre-populates it with
data set within the controller.
It should be pretty easy. When "editing", in the view just check if
the image path is set and then display it.
<?php if (!empty($data['Model']['image'])) {
echo $this->Html->image($data['Model']['image'], array('alt' => ''));
} ?>
Along side this you will also display the file upload input. Then in
the controller you just check if the file input is not empty, and if
it does, overwrite the previous image.
