For PDFs this function indicates the number of pages on the PDF, NOT images that might be embedded within the PDF.

<?php

$document
= new Imagick('2_pager.pdf');

var_dump($document->getNumberImages()); //returns 2

$document = new Imagick('1_pager.pdf');

var_dump($document->getNumberImages()); //returns 1

?>

From my research it is not possible to obtain the images embedded within a PDF by using the PHP Imagick library.
