DZX2.0版图片版瀑布流分享

近日看到网上流行的瀑布流，也参照改了下，但是网上的forumdisplay_list.htm都是全部替换form表单里的所有项，直接影响到的是非图片版帖子列表界面，其实没必要把form表单里的所有项都替换，仅替换“else if 图片部分+分页”部分即可。
为了完整方法跟其他帖写的都一样，为方便新手，操作如下：

1、将qing模板目录下\image\redef.js移动至正在使用模板的图片存放目录，同时将qing模板中的bg_waterfall.png、bg_pgbtn.png移动至当前模板图片目录。
2、模板目录下增加common\extend_common.css，其内容如下：
/* 大分页按钮 by Pony 1203121325 */
.pgbtn { margin: 5px 0 10px; }
.pgbtn a { display: block; height: 40px; line-height: 40px; letter-spacing: 5px; text-align: center; border: 1px solid #DCDCDC; background: #F5F5F5 url({STYLEIMGDIR}/bg_pgbtn.png) repeat-x 0 0; font-size: 14px; outline: none; border-radius: 5px; box-shadow: 0 1px 0 #F5F5F5; }
.pgbtn a:hover { border-color: #BABABA; text-decoration: none; }
.pgbtn a:active { background: #EEE; border-color: #D0D0D0; box-shadow: none; }

/* 瀑布流布局 by Pony 1204121803 */
.waterfall { position: relative; margin-top: 15px; }
.waterfall li { margin: 0 10px 10px 0; padding: 0 0 3px; text-align: left; border-width: 1px 0 0; border-top: 1px solid #EAEAEA; background: url({STYLEIMGDIR}/bg_waterfall.png) no-repeat 100% 100%; }
.waterfall .c, .waterfall h3 { padding: 10px; border: solid #EAEAEA; border-width: 0 1px; background-color: #F8F8F8; }
.waterfall .c { overflow: hidden; padding-bottom: 0; max-height: 800px; }
.waterfall .c .nopic { display: block; background:{WRAPBG} url({IMGDIR}/nophototiny.png) no-repeat 50% 50%; cursor: pointer; }
.waterfall .auth { padding: 0 10px 10px; border-width: 0 1px 1px; border-style: solid; border-color: transparent #EAEAEA #B9B9B9; background: #F8F8F8; }
.waterfall .auth img { display: inline-block; margin: 0 1px; }
3、拷贝qing\forum\forumdisplay_list.htm文件里的“else if 图片部分+分页”替换default里的forumdisplay_list.htm的相应图片部分（即从<!-- end of table "forum_G" branch 2/3 --> 开始到</form>结束）。
<!--{else}-->
</table><!-- end of table "forum_G" branch 2/3 -->
<ul id="waterfall" class="ml waterfall cl">
<!--{loop $_G['forum_threadlist'] $key $thread}-->
<!--{if !$thread['forumstick'] && ($thread['isgroup'] == 1 || $thread['fid'] != $_G['fid'])}-->
<!--{if $thread['related_group'] == 0 && $thread['closed'] > 1}-->

</form>
4、后天帖子列表界面，图片宽度设为200，高度9999，相应版块开启图片版即可

5、如果你需要向下加载的话，需要把分页代码一起复制进forumdisplay_list.htm去
