depend on your code if you use it as gallery shortcode i think this will work :
<div class="gallery-content">
<?php
if( has_shortcode( $post->post_content, 'gallery' ) ) :
if ($ids != '') {
$images = explode(',', $ids);
} else {
$images = get_children(array('post_parent' => get_the_ID(),'post_type' => 'attachment','post_mime_type' => 'image', 'orderby' => 'menu_order_ID'))
}
if ($images) :
$image_list="<ul class="galleryslider">";
foreach( $images as $image ) :
if ($ids != '') {
$image = get_post($image);
}
$attachmenturl=wp_get_attachment_url($image->ID);
$attachmentimage=wp_get_attachment_image($image->ID, 'full' );
$img_title = $image->post_title;
$img_desc = $image->post_excerpt;
$image_list .= '<li><a href="'.$attachmenturl.'" '. $lightbox .' data-title="'.$img_desc.'" title="'.$img_title.'"><div class="gallery-image-title">'.$img_title.'</div>'.$attachmentimage.'</a><div class="gallery-image-desc">'.$img_desc.'</div></li>';
endforeach;
$image_list .= '</ul>';
echo $image_list;
endif;
endif;
?>
