I am trying to do the same thing. I found some code for querying the database for all the galleries from nextgen but it feels a bit hack-y.
<ul>
<?php
$galleries = array();
$query = "SELECT * FROM wp_ngg_gallery WHERE gid";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$galleries[] = $row['title'];
}
?>
<?php
$i = 1;
foreach ($galleries as &$value) {
echo '<li><a href="/?page_id=226&album=1&gallery='.$i.'">'.$value.'</a></li>';
$i++;
}
?>
</ul>
Make sure the page you are linking to (in this example page with id 226, but yours will be different) has shortcode for an album ( [ album id=1 template=compact ] ) otherwise it will not display the album.
If anyone else has a more elegant solution inside nextgen to display a list of all the galleries, let me know!
