Версия вордпресс: 3.2.1
Приветствую всех!
Проблема с плагином topcollage - хочу чтобы над фоткой в коллаже, выводилось еще ее описание (alt или description).
Как не пробовал - ничего не помогает.
Вот я так понимаю, код вывода изображений:
А вот код самого файла плагина(где имеется код который выше
Но у меня не получается что-то вывести описание изображения.
Прошу помощи у специалистов.
Заранее спасибо!

Plugin Name: topCollage
Plugin URI: http://www.topquarkproductions.ca/
Description: topCollage makes a collage out of photos added to your post.
Version: 0.5.1
Author: Trevor Mills
Author URI: http://www.topquarkproductions.ca/
=============================================================
Change Log
=============================================================
Version 0.5.0 - May 7, 2010
---------------------------
- initial check-in
Version 0.5.1 - July 15, 2010
---------------------------
- Fixed problem that had all attached images appearing in feed as opposed
to just showing the collage. Unfortunately, feeds can't be guaranteed to
use styles, so instead of just outputing all images, we'll display only
the first image in each collage
