In my previous post, I had explained how to display product information on mouse over thumbnail – http://w3lessons.info/2013/04/03/display-product-information-on-a-hover-over-thumbnails-using-jquery/

Now a days most websites are using this trick. In this tutorial You are going to show a link icon on mouse over anchored thumbnail, showing play icon on mouse over video thumbnail & showing Zoom icon on gallery thumbnails.

jQuery Code

jQuery(window).load(function() {

                  var image_item=jQuery("a.image_effect");

                  image_item.each(function(){

                           var img_width = jQuery(this).find('img').width();
                           var img_height = jQuery(this).find('img').innerHeight();
                           var imageClass = jQuery(this).attr("class");
                           jQuery(this).prepend('<span class="imagemask '+imageClass+'"></span>');

                           var p = jQuery(this).find('img');
                           var position = p.position();
                           var PosTop= parseInt(p.css("margin-top"))+position.top;
                           var PosLeft= parseInt(p.css("margin-left"))+position.left;
			   			   if (!PosLeft) {PosLeft= position.left};

                           jQuery(this).find('.imagemask').css({top: PosTop});
			   	  jQuery(this).find('.imagemask').css({left: PosLeft});

                           jQuery('.imagemask', this).css({width:img_width,height:img_height,backgroundPosition:'center center'});
                           //for IE Browser
                           if(jQuery.browser.msie){ jQuery('.imagemask', this).css({display:'none'});}

                  });

         });

        var image_effect= jQuery("a.image_effect");
		//ignore the shadow effect if browser IE
		if(jQuery.browser.msie){

				image_effect.mouseover(function(){

				jQuery(this).find('.imagemask').stop().css({
						  display:"block", "z-index":"400"
						  });

				}).mouseout(function(){
					jQuery(this).find('.imagemask').stop().css({
						 display:"none","z-index":"0"
						} );
				});

		}else{
			//other browsers
			 image_effect.mouseover(function(){
			 jQuery(this).find('.imagemask').stop().animate({
					   display:"block",
					   opacity:1,
					   "z-index":"400"
					   }, 100);
			  jQuery(this).find('img').stop().animate({
					   opacity: 0.7
			}, 200);
			 }).mouseout(function(){
				 jQuery(this).find('.imagemask').stop().animate({
					   display:"none",
					   opacity:0,
					   "z-index":"0"
					 }, 100 );
				 jQuery(this).find('img').stop().animate({
					   opacity: 1
			}, 300);
			 });
		}
