just put this in a php file, you'll know what to do next,won't work on a windows server though

PHP Code:


<?php
# folder from the document_root you want to include and all sub dirs
 $folder = "images";
    function createimagearray($newdir){
     global $folder,$newarray,$DOCUMENT_ROOT;
     $dir_subdirs = array();
     chdir($newdir);

     $handle = opendir($newdir);

        while($entry = readdir($handle)){
         $dirtitle = str_replace($DOCUMENT_ROOT,"",$newdir);
         $last4 = substr(strtolower($entry),-4);
            if(is_dir($entry) && $entry != ".." && $entry != "."){
             $dir_subdirs[] = $entry;
            } elseif($entry != ".." && $entry != "." && ($last4 == ".gif" || $last4 == ".jpg" || $last4 == ".png" || $last4 == ".bmp")){
             $newarray .= "$dirtitle$entry||";
            }
        }
     sort($dir_subdirs);
           for($i=0; $i<count($dir_subdirs); $i++){
         $array = createimagearray("$newdir$dir_subdirs[$i]/");
        }
     closedir($handle);
     return $newarray;
    }
 $array    = createimagearray($DOCUMENT_ROOT."/".$folder."/");
 $array = substr($array, 0,-2);
 $array = explode("||",$array);
    function make_seed() {
     list($usec, $sec) = explode(' ', microtime());
     return (float) $sec + ((float) $usec * 100000);
    }
 srand(make_seed());
 $view = $array[rand(0,(count($array))-1)];
 echo "<img src=\"$view\">";
?>

tell me if it doesn't work though, cause i want to use it for other things as well, and my localhost isn't working at the moment, plus i'm quite a php n00b, this wasn't made for forum use though, just a seperate script, but i'm sure you can get it to work
