Latest version broke gallery with Fancybox

After deeper investigation I’ve found “conflict” with lazyload plugins resulting such behavior.

Lazyloads typicaly injects two pieces of code for each image (one for js, another – for non-js users), lightbox reacts on both of them, resulting creation of fake gallery containing just two same images.

JFYI, devs, please try to workaround this issue, it is not really complicated. ??

Thanks,
Sergey

One more problem which I always forget to declare is one small issue in fancybox css, which leads old IE users (like ie6/7/8/9) to have missed control icons (arrows, shadow pngs etc).

Original piece of jquery.fancybox-1.3.4.css included with your plugin looks like this:

/* IE6 */

.fancybox-ie6 #fancybox-close { background: transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='fancybox/fancy_close.png', sizingMethod='scale', enabled='true'); }

.fancybox-ie6 #fancybox-left-ico { background: transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='fancybox/fancy_nav_left.png', sizingMethod='scale', enabled='true'); }
.fancybox-ie6 #fancybox-right-ico { background: transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='fancybox/fancy_nav_right.png', sizingMethod='scale', enabled='true'); }

.fancybox-ie6 #fancybox-title-over { background: transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='fancybox/fancy_title_over.png', sizingMethod='scale', enabled='true'); zoom: 1; }

.fancybox-ie6 #fancybox-bg-w, .fancybox-ie6 #fancybox-bg-e, .fancybox-ie6 #fancybox-left, .fancybox-ie6 #fancybox-right, #fancybox-hide-sel-frame {
	height: expression(this.parentNode.clientHeight + "px");
}

#fancybox-loading.fancybox-ie6 {
	position: absolute; margin-top: 0;
	top: expression( (-20 + (document.documentElement.clientHeight ? document.documentElement.clientHeight/2 : document.body.clientHeight/2 ) + ( ignoreMe = document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop )) + 'px');
}

#fancybox-loading.fancybox-ie6 div	{ background: transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='fancybox/fancy_loading.png', sizingMethod='scale', enabled='true'); }

/* IE6, IE7, IE8 */

.fancybox-ie .fancybox-bg { background: transparent !important; }
