[@cms_content_page count='10' orderBy='4' channelId=115 channelOption='2' dateFormat='yyyy-MM-dd']
            [#list tag_pagination.list as c]


[#if c.picPaths??]
            <a href="${c.url}" target="_blank" class="pic" style="border:1px solid #ccc;">
            <img src="${c.picPaths!site.picPaths}" />
            </a>
            [/#if]
            [/#list]
        [/@cms_content_page]
