CakePHP: image inside link, want to make link point to image location

Question

I have some images inside links that I want to essentially look like this:

Answer 1

you can also do this in 1.2

echo $html->link(
    $html->image('img.png'),
    'img.png',
    array(),
    null, 
    false
  );

or in 1.3

echo $html->link(
    $html->image('img.png'),
    'img.png',
    array(),
    array( 'escape' => false ),     
  );
