#divid{
    position: fixed;
    right: 0;
    bottom: 0;
}

<style type="text/css">
    #myFixedDiv {
        position: fixed;
        bottom: 0;
        right: 0;
        ...
    }

<div id="myFixedDiv">
    <a href="#myTargetDiv"><img src="img.gif" /></a>

<div id="myTargetDiv">

<script type="text/javascript">
    var $myFixedDiv = $('#myFixedDiv');
    var iFixedDivHeight = $myFixedDiv.outerHeight({ 'margin': true });

    $(window).bind('scroll', function(e) {
        var iWindowHeight = $(window).height();
        var iScrollPosition = $(window).scrollTop(); // or document.body.scrollTop
        $myFixedDiv.css({ 'top': iWindowHeight + iScrollPosition - iFixedDivHeight });
