Randome image

[DaT]

Im looking for a randome image code. Ive seen it on a couple sites, Blinky uses it over at www.blinksworld.com

I have looked through the code but i havent got a clue what im looking for, also i've searched for a tutorial but cant find one. if anyone could give me a hand with this it would be great.

cheers - DaT

here's the code I used for http://start.neverwake.net

// get random picture from /random folder
$dir = "./".$user[skin]."/random/";
if ($handle = @opendir($dir)) {
$xx=0;
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$ranpics[$xx] = $file;
$xx++;
}
}
closedir($handle);
}
$r = explode(" ", microtime());
$rand_key = (round($r[0] * 100)) % sizeof($ranpics);
$file = $ranpics[$rand_key];
$randpictext = "$user[skin]/random/$file";

It takes how many microseconds have passed since the last second, and uses that proportion against how many files there are in the directory and rounds to the nearest integer, choosing that picture. Never liked the rand() functions cause they were never really random.

// Make this the relative path to the images, like "../img" or "random/images/".
// If the images are in the same directory, leave it blank.
$folder = '';

// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png gif';

$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';
$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
foreach($exts as $ext) { // for each extension check the extension
if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
$files[] = $file; // it's good
++$i;
}
}
}
closedir($handle); // We're not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along

header('Location: '.$folder.$files[$rand]); // Voila!
?>

For the simplest possible installation, just drop this code in a directory with the images you want to rotate, and call it like you would a normal image, for example:

<img src="/dropbox/2003/rotate/rotate.php" alt="A Random Image" />

This is the one I'm using on my site, thanks to www.photomatt.net
