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.
<?php
/* Create the object */
$image = new Imagick('YourImageLocation.tif');
$count = $image->getNumberImages();
echo "<h3 style=\"font: bold 12pt Arial\">Total Number of Images Extracted ".
"from the TIF : ".$image->getNumberImages()."</h3>";
for ($x = 1;$x <= $image->getNumberImages(); $x++) {
$image->previousImage();
$image->thumbnailImage( 400, null );
$image->writeImage('img'.$count.'.png');
$count--;
}
?>
