在子比主题设置—自定义CSS样式，添加下面的CSS代码：

textarea#comment {background-color:transparent;background:linear-gradient(rgba(0, 0, 0, 0.05), rgba(0, 0, 0, 0.05)),url(图片链接) right 10px bottom 10px no-repeat;-moz-transition:ease-in-out 0.45s;-webkit-transition:ease-in-out 0.45s;-o-transition:ease-in-out 0.45s;-ms-transition:ease-in-out 0.45s;transition:ease-in-out 0.45s;}
textarea#comment:focus {background-position-y:789px;-moz-transition:ease-in-out 0.45s;-webkit-transition:ease-in-out 0.45s;-o-transition:ease-in-out 0.45s;-ms-transition:ease-in-out 0.45s;transition:ease-in-out 0.45s;}

图片自己保存到本地，图片大小（162 X 75，建议透明的png图片）,自己添加喜欢的背景图片。

效果
