[Plugin: NextGEN Gallery] Fix for slideshow not appearing on IE 7

I cannot get the slideshow to work consistently on IE 7, it will frequently show a blank space instead of the images. Here is a possible fix which seems to work:

Open ngg.slideshow.js (or ngg.slideshow.min.js if you are using that one) and change the loadImage function by adding the check for image already loaded ( the lines after the line that starts with jQuery( img ).bind(... )

function loadImage(num){
 if(stackLength > 0 && num <= 3) {
  var img = new Image();
  img.src = stack.shift();
  stackLength--;
  // wait to append image until the load is complete
  jQuery( img ).bind('load', function() { appendImage(img, num); });
  if(img.complete || (jQuery.browser.msie && parseInt(jQuery.browser.version) <= 7))
    jQuery(img).trigger("load");
 }
}
