You might want to try PEAR's File_Find package. With it, you could pass
a pattern to match, and receive an array of files that match. You could
then use array_map() to strip the suffix:

include_once 'File/Find.php';

function photo_basename($file)
{
list($name, $sfx) = explode('.', basename($file), 2);
return $name;
}

$photos = &File_Find::glob('/.*\.(jpg|png|gif)$/i', 'photos', 'perl');
$photos = array_map('photo_basename', $photos);

To determine the number of files, simply do a count() on the $photos
array.
