CakePHP 1.2: $html->link with html or image.
In CakePHP 1.1 if you need to display an image or piece of HTML with a link to an action, you need to instruct cake NOT to escape the contents of the “Title” attribute with the last false statement like this:
e( $html->link( $html->image("add.gif"), array('action' => 'add'), array(), null, false ));
In CakePHP 1.2 you could rewrite this to:
e( $html->link( $html->image("add.gif"), array('action' => 'add'), array('escape' => false)));



great tip, thank you.
