建议到js版块找一找.

<script type="text/javascript">
<!--
var j = 0;
function foto() {
    var a = ["1.jpg", "2.jpg", "3.jpg", "4.jpg"];
    j++;
    if (j >= a.length) j = 0;
    if (document.getElementById) {
    document.getElementById('screenshot').src = a[j];
        return false;
    }
}
-->
</script>

<a href="2.jpg" title=""><img id="screenshot" src="1.jpg" alt="" onclick="return foto()"/></a>
