样式倍儿全的img标签

<ul style="list-style: none; padding-left: 0px ; padding-right: 0px;"><s:iterator begin="1" end="8" step="1" var="item"><li ><a href="#"><img src="${pageContext.request.contextPath }/tcmpicture_show.action?pictureId=<s:property value="pictureId"/>&flag=<s:property value="#item"/>" onerror="javascript:this.src='${pageContext.request.contextPath}/images/defaultPhoto.gif'" onmouseover="this.style.border='solid 2px blue'" onmouseout="this.style.borderStyle='none'"  style="border-bottom: 30px;"/>     </a></li><div> </div></s:iterator></ul>

默认图片，移进去进边框，移出后去掉边框效果
