HTML

<form name="" method="post" action="#" class="feedback-form-1">
    <fieldset>
        <div class="input-file-row-1">
            <div class="upload-file-container">
                <img id="preview_image" src="#" alt="" />
                <div class="upload-file-container-text">
                    <div class = 'one_opacity_0'>
                        <input type="file" id="patient_pic" label = "add" />
                    </div>
                    <span> Add Photo </span>
                </div>
            </div>
        </div>
    </fieldset>
</form>

查询：

function readURL(input, target) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();
        var image_target = $(target);
        reader.onload = function (e) {
            image_target.attr('src', e.target.result).show();
        };
        reader.readAsDataURL(input.files[0]);
     }
 }

 $("#patient_pic").live("change",function(){
    readURL(this, "#preview_image")
 });

CSS：

.input-file-row-1:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

.input-file-row-1{
    display: inline-block;
    margin-top: 25px;
    position: relative;
}

#preview_image {
  display: none;
  width: 90px;
  height: 90px;
  margin: 2px 0px 0px 5px;
  border-radius: 10px;
}

.upload-file-container { 
    position: relative; 
    width: 100px; 
    height: 137px; 
    overflow: hidden;   
    background: url(http://i.imgur.com/AeUEdJb.png) top center no-repeat;
    float: left;
    margin-left: 23px;
} 

.upload-file-container-text{
    font-family: Arial, sans-serif;
    font-size: 12px;
    color: #719d2b;
    line-height: 17px;
    text-align: center;
    display: block;
    position: absolute; 
    left: 0; 
    bottom: 0; 
    width: 100px; 
    height: 35px;
}

.upload-file-container-text > span{
    border-bottom: 1px solid #719d2b;
    cursor: pointer;
}

.one_opacity_0 {
  opacity: 0;
  height: 0;
  width: 1px;
  float: left;
}
