endless marquee

Ok I have this html

        <marquee scrollamount="6">
            <a href="javascript:void(0)" ><img src="images/banner/03.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/04.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/05.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/06.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/07.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/03.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/04.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/05.gif" /></a>
            <a href="javascript:void(0)" ><img src="images/banner/06.gif" /></a>
            <a href="javascript:void(0)" &g开发者_JAVA技巧t;<img src="images/banner/07.gif" /></a>
        </marquee>

this marque moves my images from right to left.

my question is, is there a way to know if the element is hidden already?

I'm planning to get the element that goes out of view then append it as last element of <marquee>. I want to get an endless marquee. Please help me, I'm stuck.

Use jquery + marquee plugin like http://remysharp.com/2008/09/10/the-silky-smooth-marquee/

<marquee> tag is deprecated:

The marquee tag is a non-standard HTML element which causes text to scroll up, down, left or right automatically. The tag was first introduced in early versions of Microsoft's Internet Explorer, and was compared to Netscape's blink element, as a proprietary non-standard extension to the HTML standard with usability problems. It is deprecated by the W3C and not advised by them for use in any HTML documents.
