Published in: PHP 

It gets images randomly from folder that you've pointed.

  12. if($_GET['folder']){ 
  13.      $folder=$_GET['folder']; 
  14. }else{ 
  15.      $folder='/images/'; 
  16. } 
  17.  
  18. //Selected Folder Name
  19. $path = $_SERVER['DOCUMENT_ROOT']."/".$folder; 
  20. $files=array(); 
  21. if ($handle=opendir("$path")) { 
  22.      while(false !== ($file = readdir($handle))) {   
  23.           if ($file != "." && $file != "..") {  
  24.                      if(substr($file,-3)=='gif' || substr($file,-3)=='jpg') $files[count($files)] = $file; 
  25.                 } 
  26.            }  
  27. } 
  28. closedir($handle);  
  29.  
  30. $random=rand(0,count($files)-1); 
  31. if(substr($files[$random],-3)=='gif') header("Content-type: image/gif"); 
  32. elseif(substr($files[$random],-3)=='jpg') header("Content-type: image/jpeg"); 
  33. readfile("$path/$files[$random]"); 
  34. ?>
  35.  
  36. Usage :
  37. It's very easy to use. Just copy the code to a new php file and save it "randomImages.php". 
  38.  
  39. Then where ever you would like to use and show your random images, use this way and don't forget to add folder name to a string.
  40. <img src=randomImages.php?folder=randomFolder02/>
