I have the following code to output images from directory im/, how can I tweak this to also output images from another diectory called out/ (for example)? As to echo another img tag under the current one?

<?php
    $imgDir = "im/";

    $images = scandir($imgDir); 
    $ignore = array( ".", ".." ); 

    natsort($images);

    foreach($images as $file)
       {
    if(!in_array($file, $ignore))
       {
    echo "<div id=\"slideWrapper\">\n";
    echo "<img src=\"im/$file\" width=\"1000\" height=\"683\" alt=\"$files\" />\n";
    echo "</div>\n";
    };
    }
?>
