overflow和absolute之间的问题，transfrom可以解决

CSS代码：

.overflow { width: 191px; height: 191px; border: 2px solid #beceeb; overflow: hidden; }
.overflow img { position: absolute; }
.transform { -webkit-transform: scale(1); -ms-transform: scale(1); transform: scale(1); }

HTML代码：

<p><strong>图片自身transform</strong></p>
<div class="overflow">
    <img src="mm1.jpg" class="transform" />
</div>
<p><strong>overflow容器transform</strong></p>
<div class="overflow transform">
    <img src="mm1.jpg" />
</div>
<p><strong>overflow和图片之间内嵌元素transform</strong></p>
<div class="overflow">
    <div class="transform">
        <img src="mm1.jpg" />
    </div>
</div>
