自定义的函数（onethink里cover_id这个函数自己改的，cover_id原来的函数是取单个图片，现在需求是取多个图片）
{:get_covers($list[cover_ids],path)}
下面是取出的结果
array(5) {
[0] => string(52) "/1y20/1/Uploads/Picture/2015-12-07/566530fe92dba.jpg"
[1] => string(52) "/1y20/1/Uploads/Picture/2015-12-07/56653b2da08bb.jpg"
[2] => string(52) "/1y20/1/Uploads/Picture/2015-12-07/56655ae7cd9f2.jpg"
[3] => string(52) "/1y20/1/Uploads/Picture/2015-12-07/56655b0bc4770.jpg"
[4] => string(52) "/1y20/1/Uploads/Picture/2015-12-07/56659f96149ec.jpg"
}
