CSS
画一个方框和一个按钮
绑定按钮的点击事件为触发file的点击事件
把file的onchange事件返回的文件名称设置到第一个方框里
以jquery为例
$("#btn").bind("click", function(e){
$("#file").trigger("click");
return false;
});
$("#img-file").bind("change", function(){
//设置取到的文件名至第一个box
});

.messageTxt span.fileInputContainer{background:url(images/这里改成你自己的图片.jpg) no-repeat 0 8px;position:relative;width:57px;}
.fileInput{height:24px;overflow: hidden;font-size:300px;position:absolute;right:0;top:0;opacity: 0;filter:alpha(opacity=0);cursor:pointer;}
多谢各位的帮忙
