I've created an image gallery with the preview image popup on hover.

http://jsfiddle.net/WSfka/

Hover over the thumbnail images and the larger image preview displays.

I'm not happy with the way preview images can flash between moving around the thumbnail images. How can I simplify the script and improve the preview image popup?

$(document).ready(function() {
    $('.imageGalleryAlbum li a img').mouseenter(function() {
        $(this).closest('li').find('.preview').delay(500).fadeIn(1);
        $(this).closest('li').siblings().find('.preview').fadeOut(1);
        return;
    });
    $('.imageGalleryAlbum li .preview').hover(function() {
        $(this).closest('li').siblings().find('.preview').fadeOut(1);
        return;
    });
    $('.imageGalleryAlbum li .preview').mouseleave(function() {
        $(this).closest('li').find('.preview').fadeOut(1);
        $(this).closest('li').siblings().find('.preview').fadeOut(1);
        return;
    });
    $('.imageGalleryAlbum li .preview').click(function() {
        $(this).closest('li').find('.preview').fadeOut(1);
        $(this).closest('li').siblings().find('.preview').fadeOut(1);
        return;
    });
});

$(document).mouseup(function(e) {
    var container = $(".preview");
    if (container.has(e.target).length === 0) {
        container.fadeOut(1);
    }
});?
