Ok, i have had a number of PMs and stuff about people who are confused about my Signiture, so i have made this post to explain.

Firstly, the signiture is one that randomly shows 1 of 10 images i have made, as shown below:

1
2
3
4
5
6
7
8
9
10

If anyone else wants to do this, You have to have a folder on a webserver, and then put this file into the folder, along with any images you have.

FYI the code is also below:

<?php

/*

        INSTRUCTIONS
    1. Modify the $folder setting in the configuration section below.
    2. Add image types if needed (most users can ignore that part).
    3. Upload this file (rotate.php) to your webserver.  I recommend
       uploading it to the same folder as your images.
    4. Link to the file as you would any normal image file, like this:

            <img src="http://example.com/rotate.php">

    5. You can also specify the image to display like this:

            <img src="http://example.com/rotate.php?img=gorilla.jpg">
        
        This would specify that an image named "gorilla.jpg" located
        in the image-rotation folder should be displayed.
    
    That's it, you're done.

*/




/* ------------------------- CONFIGURATION -----------------------


    Set $folder to the full path to the location of your images.
    For example: $folder = '/user/me/example.com/images/';
    If the rotate.php file will be in the same folder as your
    images then you should leave it set to $folder = '.';

*/


    $folder = '.';


/*    

    Most users can safely ignore this part.  If you're a programmer,
    keep reading, if not, you're done.  Go get some coffee.

    If you'd like to enable additional image types other than
    gif, jpg, and png, add a duplicate line to the section below
    for the new image type.
    
    Add the new file-type, single-quoted, inside brackets.
    
    Add the mime-type to be sent to the browser, also single-quoted,
    after the equal sign.
    
    For example:
    
    PDF Files:

        $extList['pdf'] = 'application/pdf';
    
    CSS Files:

        $extList['css'] = 'text/css';

    You can even serve up random HTML files:

        $extList['html'] = 'text/html';
        $extList['htm'] = 'text/html';

    Just be sure your mime-type definition is correct!

*/

    $extList = array();
    $extList['gif'] = 'image/gif';
    $extList['jpg'] = 'image/jpeg';
    $extList['jpeg'] = 'image/jpeg';
    $extList['png'] = 'image/png';
    

// You don't need to edit anything after this point.


// --------------------- END CONFIGURATION -----------------------

$img = null;

if (substr($folder,-1) != '/') {
    $folder = $folder.'/';
}

if (isset($_GET['img'])) {
    $imageInfo = pathinfo($_GET['img']);
    if (
        isset( $extList[ strtolower( $imageInfo['extension'] ) ] ) &&
        file_exists( $folder.$imageInfo['basename'] )
    ) {
        $img = $folder.$imageInfo['basename'];
    }
} else {
    $fileList = array();
    $handle = opendir($folder);
    while ( false !== ( $file = readdir($handle) ) ) {
        $file_info = pathinfo($file);
        if (
            isset( $extList[ strtolower( $file_info['extension'] ) ] )
        ) {
            $fileList[] = $file;
        }
    }
    closedir($handle);

    if (count($fileList) > 0) {
        $imageNumber = time() % count($fileList);
        $img = $folder.$fileList[$imageNumber];
    }
}

if ($img!=null) {
    $imageInfo = pathinfo($img);
    $contentType = 'Content-type: '.$extList[ $imageInfo['extension'] ];
    header ($contentType);
    readfile($img);
} else {
    if ( function_exists('imagecreate') ) {
        header ("Content-type: image/png");
        $im = @imagecreate (100, 100)
            or die ("Cannot initialize new GD image stream");
        $background_color = imagecolorallocate ($im, 255, 255, 255);
        $text_color = imagecolorallocate ($im, 0,0,0);
        imagestring ($im, 2, 5, 5,  "IMAGE ERROR", $text_color);
        imagepng ($im);
        imagedestroy($im);
    }
}

?>

Have fun!
