Image Rotation?

[ShadowStriker]

I have seen this before, but I don't know how they did it. I think they put a link to a folder (on the internet) or something with all their sigs in, and then every couple seconds (when you refresh) it switches sigs to a different one in that folder. How do you do this?

Okay , heres how you do it.

Create a Php file named "random_image.php" with this code

<?php

// print a random image. Don't forget ending slash!
// setting $type to 'all' will return all images.

function getRandomImage($dir,$type='random')
{
global $errors,$seed;

if (is_dir($dir)) {

$fd = opendir($dir);
$images = array();

while (($part = @readdir($fd)) == true) {

if ( eregi("(gif|jpg|png|jpeg)$",$part) ) {
$images[] = $part;
}
}

// adding this in case you want to return the image array
if ($type == 'all') return $images;

if ($seed !== true) {
mt_srand ((double) microtime() * 1000000);
$seed = true;
}

$key = mt_rand (0,sizeof($images)-1);

return $dir . $images[$key];

} else {
$errors[] = $dir.' is not a directory';
return false;
}
}

?>


Create a folder on your site called something like "sigimages" and place it in there.

Then create another php file called "images.php" with this code

<?php
require_once("random_image.php");
$pic = getRandomImage('path/to/images/');
?>


replace path/to/images/' with the path to the folder the images are in.

Place the "images.php" in the same folder as "random_image.php" and also place all your pictures in there.

Then in your bbc sig code use this code

[img]http://yoursite.com/sigimages/image.php[/img]


Obviously replace the  link to your image.php address.
