title: Jquery image overlay gallery parameter issue
body: <p>I'm using <a href="http://buildinternet.com/project/mosaic/1.0/" rel="nofollow">the mosaic sliding boxes and captions plugin</a>. It's pretty smooth but I'd love to fix two problems, visible on this jfiddle. Some CSS/jQuery wiz here will know:</p>

  <p>1) The overlay box doesn't cover the bottom of the image. I've fiddled with many of the obvious parameters in the CSS and jQuery. This problem has emerged because I add the hover_y parameter in my inline script. That is designed to raise the overlay higher so more text becomes visible.</p>
  
  <p>2) The opacity only changes when you hover on the overlay, but it would be good if it changed wherever you are over the image, which is what the slide responds to.</p>
  
  <p>I've already tried many of the obvious parameters, I'm hoping someone here can help.</p>
  
  <p>Thanks</p>
