[support] How to show different images on page refresh

[Austin Einter]

Hi All
Finally the below code I added to page.tpl.php to show different images at
on page refresh.
In IE8 it is working fine. Howevr with firefox the image is not shownup. Any
clue ?

The code is as below.

 <!--    Starting banner  -->
<?php
function endswith($string, $test)
{
 $strlen1 = strlen($string);
 $testlen = strlen($test);
 if($strlen1 < $testlen)
  return FALSE;
 $diff = $strlen1 - $testlen;
 $strend = substr($string, $diff);
 return ($strend == $test);
}
$dirimage = realpath('.\sites\all\themes\myzen\templates\himg');
$directory = opendir($dirimage);
$counter = 0;
while ( FALSE !== ($file = readdir( $directory )) )
{
 if(endswith($file, "jpg"))
 {
  $counter++;
  $files[] = $file;
 }
}
$counter--;
$which   = rand(0,$counter) ;
$imagepath = $dirimage . "\\" . $files[$which];
?>
<img src="<?php print $imagepath ?>" />
