I have a gallery attached to a page. On that page, I'm running the following query:

$events_gallery = new WP_Query( // Start a new query for our videos
array(
    'post_parent' => $post->ID, // Get data from the current post
    'post_type' => 'attachment', // Only bring back attachments
    'post_mime_type' => 'image', // Only bring back attachments that are images
    'posts_per_page' => '3', // Show us the first three results
    'status' => 'inherit', // Inherit the status of the parent post 
    'orderby' => 'rand', // Order the attachments randomly  
    )
);

I've experimented quite a few ways and, for some reason, I can't get attachments to return. Am I missing something obvious here?
