after six attempts to beg the original javascript auhtor code to make it script compatible with newer jQuery libraries, all six are in vain, I decided it was time for me to fix this without him a seventh attempt, and getting rid of it otherwise worked fine (after numerous settings for me) image popup script.

Problem: It works when JQuery 1.3.2 ~ 1.4.2 loads , but NOT when JQuery 1.4.3 ~ 1.5.1 . In new builds, images do not increase after clicking on the thumbnails, whereas on old builds do!

Any suggestion / help is kindly appreciated and greatly appreciated by me. Thank!

The problem is here:

//display content
var displayContent = function(img) {
    if (visible) {
        var newImg = jQuery.extend(true, {}, img);
        resizeImg(newImg);

        var imgWidth = newImg.width;
        var imgHeight = newImg.height;
        var outerWidth = imgWidth + hBound;
        var outerHeight = imgHeight + vBound; 

        $lightbox.stop(true).animate({width:imgWidth, height:(imgHeight + cpHeight),
        left: Math.round(($(window).width() - outerWidth)/2),
        top:Math.round(($(window).height() - outerHeight)/2)}, 
        tranSpeed, 
        function() {
            enableCtrl();
            $innerBox.height(imgHeight);
            $info.html(langArrows + "  " + langImage + " " + (currIndex+1) + "/" + numItems);
            $cpanel.css({top:imgHeight, display:"block"});
            $mainImg.css({width:imgWidth, height:imgHeight})
            .attr("src", newImg.src).animate({opacity:1}, tranSpeed, startTimer);
            showDesc();
        }
        );
    }
}
