title: Zoom image lightbox
body: <p>I'm looking for a lightbox jQuery plugin which scales clicked images just like Highslide does <a href="http://highslide.com/#examples" rel="nofollow">http://highslide.com/#examples</a> but it has to be small (Highslide's core is 57kb) and responsive.
  It can be very simple. I don't need galeries etc.</p>
  
  <p>Do you know good alternatives?</p>
