Show random image

Daniel · 02-21-2008, 11:00 AM

Someone asked for a script that would show a random image, only took a few minutes to write, so I thought I might as well share it here.

PHP Code:

  <?php

 
/**

 * Danltn | http://danltn.com/

 * No warranty is given to code used.

 * I'm scared of lawsuits.

 */

 
$images = array();

 
$images[] = 'http://www.escapistmagazine.com/global/media/images/articles/folder/120/zeropunctuation_logo.png';

$images[] = 'http://www.google.com/images/experimental.gif';

$images[] = 'http://www.w3.org/2001/tag/2007/05/TagThursDiagram1.JPG';

 
// Add as many as you like here.

 
$image = $images[rand(0, count($images) - 1)];

// Get random image.

 
switch (strtolower(substr($image, -4, 4)))

{

    case "jpeg":

    case ".jpg":

        $ctype = "image/jpg";

        break;

    case ".gif":

        $ctype = "image/gif";

        break;

    case ".png":

        $ctype = "image/png";

        break;

}

// Find the content type, based on the last 4 characters, I could add GDLib here, but I haven't, this was a quick script.

 
$file = @file_get_contents($image);

// Get the file

????: NamePros.com http://www.namepros.com/code/435390-show-random-image.html
 
if ($file)

{

    // Only if the file has successfully been 'grabbed'.

    $len = strlen($file);

    // Get the length to be kind to the browser.

    if (!headers_sent())

    {

        header("Pragma: public");

        header("Expires: 0");

????: NamePros.com http://www.namepros.com/showthread.php?t=435390
        header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

        header("Cache-Control: public");

        // Set headers.

        header("Content-Type: $ctype");

        // Set content type as correct image.

        header("Content-Length: " . $len);

        // Be kind to the browser by saying the length.

 
        echo $file;

        // If it all checks out, send the image.

    }

}

 
?>
