What I would like to do is create a snippet that gets the first image of every gallery
)
<div class="whatever"> <div class="image">[[MaxiGallery? &gal_query_ids=`[+id+]` &limit=`1`]]</div> <div class="info">[+yourtvname+]</div> </div>
<?php
/* parameters:
* &tpl - chunk for formatting the output
* &coverField - maxigallery-customField, if isset only pics with 'on' are displayed
* &documents - if isset, only pictures of these galleries are displayed
* &parents - if isset, only pictures from childgalleries of parents are displayed
* &depth - depth from parents
* &galLimit - limits pictures for each gallery
* &random - gets a random images for each gallery
*
* call-example:
* [!maxiviewer? &tpl=`myViewerTpl`&coverField=`cover`&documents=`45,46,47`!]
* [!maxiviewer? &tpl=`myViewerTpl`&parents=`[*id*]`&galLimit=`1`&random=`1`!]
*
* chunk-examples:
* <a href="[~[+gal_id+]~]">
* <img src="[+path_to_gal+]thumb_[+filename+]"/>
* </a>
*
* <img alt="[+pagetitle+]" src="[+path_to_gal+][+filename+]" width="[+picture_width_normal+]" height="[+picture_height_normal+]"/>
