>> 2010-/08/18 : (Thanks to Alesa Dam ) : Press the shift (MAJ) while hovering a thumbnail, if I you want shows the preview  . This way you can decide yourself when to see a bigger picture or not.

>> 2010-/08/16
- Added support to Autopager ...by inserting at the end of the script :
  window.addEventListener('AutoPagerAfterInsert', function(){PopupImage.load(); }, false);
  Now no needs to click on the blue button (must find a way to convert it in a On/Off button...)

>> 2010/08/13
- Idea of Alesa Dam :  changed line 314 from this:"//img[@class='pc_img' or @class='setThumb' or @class='nextprev_thumb' ]"
  into this:"//img[(@class='pc_img' or @class='setThumb' or @class='nextprev_thumb') and not(contains(@src,'/cols/') or contains(@src,'_z.jpg'))]"
  to make it ignore collection mozaics (which contain '/cols/' in the src attribute) and 640px wide medium images (which contain '_z.jpg' int the src)
 
  
>> 2010/08/12
- just tweak Design by decembre (no new functions)
