How to add a Back Button

Hi All
Is there a way to add aback Button to Backlight 5 Pages?

You can use this: <button onclick="window.location.href = '...'">Go Back</button>

If you want to use this on all albums, you can do this with some phplugins magic:

function album_top(){
   echo '<button onclick="window.location.href = \'...\'">Go Back</button>';
