Removing Image after some days?

请帮我一下。

示例我有以下的图像代码,并希望下面的图像在5天后被删除,如何进一步编码?

    <imgsrc="http://www.quackit.com/pix/milford_sound/milford_sound_t.jpg" style="max-width:100%" alt="Milford Sound in New Zealand" /> 

该代码中应该添加什么代码才能使该图像在5天后删除??

删除给定URL的任何(1个或多个)IMG标签:

<img src="http://quackit.com/pix/milford_sound/milford_sound_t.jpg"; 
    style="max-width:100%" alt="Milford Sound in New Zealand" />

从JavaScript页面中添加以下代码:

<script type='text/javascript'>
function removeThatImg() {
    var ex=document.getElementsByTagName("img");
    for (var i=0;i<ex.length;i++) {
        if ( ex[i].src == "http://quackit.com/pix/milford_sound/milford_sound_t.jpg" )
            ex[i].parentNode.removeChild(ex[i]);
    }
}
var dateStart = Date.parse('March 16, 2013')/86400000;
var dateNow = new Date();
dateNow = dateNow.getTime()/86400000;
if ( dateNow - dateStart > 5) // more than 5 days 
    window.onload=function() {
        //do it with a half second delay, because google may take time to add that image
        //and right after the page is loaded it may not yet be there
        setTimeout(removeThatImg,500);
    }
</script>

它只是可能工作(或可能不-我认为将是这种情况,简单地说,因为图像将是不同的每次)
