// 在图集列表中调出图集的所有图片
function Getimgs($aid, $imgwith = 220, $imgheight = 80, $num = 0, $style = ''){
global $dsql;
$imgurls = '';
$row = $dsql -> getone("Select * From`dede_addonimages` where aid='$aid'"); //
$imgurls = $row['imgurls'];
preg_match_all("/{dede:img (.*)}(.*){\/dede:img/isU", $imgurls, $wordcount);
$count = count($wordcount[2]);
if ($num > $count || $num == 0){
$num = $count;
}
for($i = 0;$i < $num;$i++){
if($style == 'li'){
$imglist .= "<li><a href=#" . $i . "><imgsrc=". trim($wordcount[2][$i]) . " width=" . $imgwith . " height=" . $imgheight . "></a></li>";
}else{
$imglist .= "<li><img class='lazy' src='../images/grey.gif' data-original=". trim($wordcount[2][$i])." width=" . $imgwith . " height=" . $imgheight . "></li>";
//此处用到了jquery的loadlazy延时加载插件。
}
}
return $imglist;
}

[field:id function="Getimgs(@me,220,80,90)" /]

{dede:arclist row='3'} // row=3 调用三个图集
[field:id function="Getimgs(@me,136,62,4)" /] //每个图集调用前4张
{/dede:arclist}在include/common.func.php 中添加以下函数代码
