PHP image website script

I have a webcam that uploads images with random names every 3 seconds. I need 3 things: 1) Find second newest image (not newest as sometimes this isn't fully uploaded when it is fetched). This then must be updated every 3 seconds while website is open - without web page refreshing, only image. Timestamp showing date and time image was created in GMT to be included under image. 2) Create looping animation of previous 60 newest JPG images (from oldest to newest) at a speed of 3 images per second 3) Display 60 newest images from oldest to newest in a list . Timestamp showing date and time image was created in GMT to be included under each image. Code to help: I have used this PHP to find the newest image - but not the second newest image: <?php $base_url = 'page/images'; $newest_mtime = 0; $show_file = 'page/images/[login to view URL]'; if ($handle = opendir($base_url)) { while (false !== ($latestFile = readdir($handle))) { if (($latestFile != '.') && ($latestFile != '..') && ($latestFile != '.htaccess')) { $mtime = filemtime("$base_url/$latestFile"); if ($mtime > $newest_mtime) { $newest_mtime = $mtime; $show_file = "page/images/$latestFile"; } } } } echo '<img src="' .$show_file. '" alt="Latest from the web">'; ?> Also I made this loop when the image was always update with the same name, this doesn't;t work now that images have random names: <table> <tbody> <tr> <td align=”center”><img src=”[login to view URL] alt=”Image will refresh every 0 Minutes 5 Seconds” width=”640″ height=”480″ name=”tcimage0″ border=”1″ /></td> </tr> <tr> <td>This is my webcam…</td> </tr> </tbody> </table> <script type=”text/javascript” language=”JavaScript”>// <![CDATA[ var tcimages = new Array(); tcimages[0] = “[login to view URL]”; interval = 5000; function Refresh() { for (i=0; i<=0; i++) { tmp = new Date(); tmp = “?” + [login to view URL](); [login to view URL][“tcimage” + i].src = tcimages[i] + tmp; } setTimeout(“Refresh()”, interval); } Refresh(); // ]]></script> </tbody> </table>
