Retrieving links and names of images from a NextGEN gallery

Question

I want to add a list (like a cd track list) of names and links to all images next my nextgen gallery, how can I retrieve this list? (similar to the list in the select object in the Gallery Settings, in the gallery admin page)

Answer 1

You may use a function similar to below one to retrieve a list of image properties in a Next-Gen image gallery.

function wp75475_imagelist(){

//http://codex.wordpress.org/Function_Reference/is_plugin_active
include_once( ABSPATH . 'wp-admin/includes/plugin.php' );

if(!is_plugin_active('nextgen-gallery/nggallery.php')){
    return 'NextGen Gallery Plugin is needed to display imagelist';
}

$imagegallery = new nggdb();
$images = $imagegallery->get_gallery('cdtrack');
$imagelist = '';

foreach ($images as $image):
    $imagelist .= $image->$filename;
endforeach;

return $imagelist;

}

For a list of retrievable image properties see properties of nggImage object.

/nextgen-gallery/lib/image.php

Ok, this has worked for me.

<?php 
// get the track list 
global $nggdb;
    $gallery = $nggdb->get_gallery ($galleryID, 'sortorder', 'ASC', true, 0, 0);
?>
<div id="tracklist">
<?php foreach($gallery as $image) { ?>
<div class="single_image" id="image-<?php echo $image->pid; ?>">
    <a href="<?php the_permalink() ?>&pid=<?php echo $image->pid;?>" title="<?php echo $image->title; ?>">
        <?php echo $image->alttext; ?>
    </a>
</div>
<?php } ?>
</div>
