How about something like this? (Defaults to the current directory)
<?php
function findImages($dir=".",$recurse=TRUE,&$a=array()){
if($dh = @opendir($dir)){
while(($item = readdir($dh)) !== false){
if($item != "." && $item != ".." && $item{0} != "."){
if(is_file($curPath=$dir.'/'.$item)){
if(preg_match('/\.(jpe?g|png|gif)$/i',$item))
$a[]=$curPath;
} else {
$recurse && findImages($curPath,$recurse,$a);
}
}
}
closedir($dh);
}
return $a;
}
$dirImages = findImages();
$randImage = $dirImages[array_rand($dirImages,1)];
if(isset($_GET['image'])){
@header("Location: $randImage");
exit;
}
$props = getimagesize($randImage);
echo "<img src=\"$randImage\" {$props[3]} alt=\"A random image\" />\n";
?>
