@AaronW. - I'm guessing that would probably make a good answer, although there are other ways too. — Jared Farrish

Pass a directory to scandir to get an array of all files in that directory. Maybe use array_filter then to filter out any non-images by file extension.

    $files = scandir( '/image/path' );

    function images_only( $file )
    {
      return preg_match( '/\.(gif|jpg|png)$/i', $file );
    }

    $files = array_filter( $files, 'images_only' );

$files should now contain only the images from the image path.

glob it

edited with array_rand fix

$images = glob("images/*.jpg");
// may want to verify that the $images array has elements before echoing
echo '<style>body{background:url('.$images[array_rand($images)].') no-repeat;';

Is the path correct? Try debugging to make sure it's populating correctly

array_rand() returns a random key only.
