I designed this specifically as a random picture generator, but im sure it can be used for many things. You make a directory with the pictures that you want to randomly select. Using this funciton, you just use the directory as the aurgument and it returns the path of a random file in that directory.

<?PHP

                            
 /*  this will take the directory you call an dreturn a random file in it  */


                            
 function randompic ($dir)

                            {
 /* this opens the directory and reads its contents into an array called $logo */

                             $handle=opendir($dir);

                            while (false !== ($file = readdir($handle))) { 

                                if ($file != "." && $file != "..") { 

                                    $logo[] = $file;

                                }

                            }

                            
 /* gets a random filename out of the $logo array */
 $randArrayKey = array_rand($logo); 
 $randFile = $logo[$randArrayKey];

                            
 /* puts the directory and the filename together */
 $path = $dir . $randFile;

                            
 /* returns the full path of the file */
 return($path);

                            }
 ?>
