Internet Explorer不显示我的图片

Question

我正在制作此网站http://projects.knord.dk/grjenie31/home.aspx 在左侧的徽标下面应该有一些赞助商的照片......但它们不在那里:( 我正在使用javascript来适应这个地方的大小。

<script type="text/javascript">
        $(document).ready(function () {
            $("img.add").each(function () {
                $(this)
     .show()
     .css('visibility', 'hidden');
                $(this).load(function () {
                    var maxWidth = 190; // Max width for the image
                    var maxHeight = 80;    // Max height for the image
                    var ratio = 0;  // Used for aspect ratio
                    var width = $(this).width();    // Current image width
                    var height = $(this).height();  // Current image height

                    // Check if the current width is larger than the max
                    if (width > maxWidth) {
                        ratio = maxWidth / width;   // get ratio for scaling image
                        $(this).css("width", maxWidth); // Set new width
                        $(this).css("height", height * ratio);  // Scale height based on ratio
                        height = height * ratio;    // Reset height to match scaled image
                        width = width * ratio;    // Reset width to match scaled image
                    }

                    // Check if current height is larger than max
                    if (height > maxHeight) {
                        ratio = maxHeight / height; // get ratio for scaling image
                        $(this).css("height", maxHeight);   // Set new height
                        $(this).css("width", width * ratio);    // Scale width based on ratio
                        width = width * ratio;    // Reset width to match scaled image
                    }
                    $(this).css('visibility', 'visible');
                })
            });
        });
    </script>

有没有人知道他们为什么会失踪？
