You could try something like this:

<?php
$path = $_SERVER['DOCUMENT_ROOT'].'/randImages';
$roll = rand(1, count(glob("$path/*.jpg"));
print "<img src='/randImages/Bn$roll.jpg' alt='...'>\n";
?>

glob() searches a given directory for filenames matching the wildcard
pattern (in this case *.jpg). It returns an array with all found
filenames. count() then simply returns the array's size and passes it to
rand().
