[jQuery] closures and for loop question, NS_ERROR_XPC_BAD_CONVERT_JS

[Joel]

JQuery users,

I'm receiving the following error:

Error: [Exception... "Could not convert JavaScript argument arg 0
[nsIDOMViewCSS.getComputedStyle]"  nsresult: "0x80570009
(NS_ERROR_XPC_BAD_CONVERT_JS)"  location: "JS frame ::
http://REMOVED.net/jquery-1.2.6.min.js :: anonymous :: line 22"  data:
no]
Source File: http://REMOVED.net/jquery-1.2.6.min.js
Line: 22

When I run this code:

$(function () {
    var imgs = $("div").filter(".fc_Picture");
    var parentDiv;
    for(i=0; i<imgs.length; i++) {
        var img = new Image();
        parentDiv = imgs[i];
        $(img)
            .load(function(parentDiv,image) {
                return function() {
                    $(image).hide()
                    $(parentDiv).removeClass('fc_loader');
                    $(parentDiv).append(image);
                    $(image).fadeIn();
                }(parentDiv,image);
            })
            .attr('src','fc_image.php?imageid='+$(imgs[i]).attr
('id').split("_")[2])
            .attr('width','50')
    }
});

What I'm trying to do is have a set of images and each one loads with
one of those cute little loader swirl things. I understand the
pitfalls of for loops and closures (after much head scratching) but I
still can't get it to work and to be honest I haven't the faintest
what that error message means.

Thanks for your help

Joel
