title: Like button issue
body: <p>I'm having a weird problem on this page www.vivopositivo.it/media/foto/guarda-chi-sorride-over-18-e-famiglie/ with the like button. I'm using PrettyPhoto to include the pictures from Flickr and open them in a lightbox. Each picture has it's own like button which shows in the lightbox and uses a specific URL such as:</p>
  
  <p>http://www.vivopositivo.it/media/foto/guarda-chi-sorride-over-18-e-famiglie/#prettyPhoto[pp_gal]/1/</p>
  
  <p>where the number in  #prettyPhoto[pp_gal]/1/ is the key for the specific image.</p>
  
  <p>The like buttons are included with the following code:</p>
  
  <p>iframe src="//www.facebook.com/plugins/like.php?locale=en_US&amp;href={location_href}&amp;layout=button_count&amp;show_faces=true&amp;width=500&amp;action=like&amp;font&amp;colorscheme=light&amp;height=23" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:500px; height:23px;" allowTransparency="true" /iframe</p>
  
  <p>where {location_href} gets replaced with the image specific URL.</p>
  
  <p>This works for most of the images, but for some of them doesn't! They seem to get the like counter of the page instead, therefore, I get about 10 images which show the same 128 like counter which is obviously wrong. This seems completely random..</p>
  
  <p>Do you have any idea on how to fix this?</p>
  
  <p>Cheers,
  Andrea</p>
