Using jquery you can do this

url = $('img').parent().attr('href');
$('img').attr('src',url);

you can add this code with some event handler. first line of code is extracting href from anchor tag and second tag is inserting it into img tag's src. This code is only a basic idea to it. You can customize it as your need.
