你都在用jQuery了为什麼要用这麽别扭的方式搞特效?
<div class="SlideWrapper" style="display:none"><img src="yourImage">
</div>
<script>
jQuery(function($)
{
$('.SlideWrapper').slideDown(4000)
})
<script>
</style><script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$('#img').animate({
width:"200%",
height:"200%",
marginLeft:"-200px",
marginTop:"-100px"
},10000)
})
</script>
<body>
<div class="showimg" id="showimg">
<img src="3.jpg" id="img" alt="Here is a pic" />
</div>
</body>
</html>
