[php] Simple random image display script
 
This is a script that I use on other boards to display a random avatar / sig image. You can get it working in a few steps: a) change the path to wherever the images are located, b) change the image names, c) plop the url of the script between some [ img ][ /img ] tags (no spaces).

LINKY (gzipped tar format): http://www.seretogis.org/files/linka...m-image.tar.gz

PHP Code:
<?

    $path = "/home/wherever/your/files/are/located/";

    $images = array (    "a.jpg",
                         "b.jpg",
                         "c.jpg"
                    );

    $x = rand( 0, ( count( $images ) - 1 ) );

    $tehfile = readfile( $path . $images[$x] );

    header( "Content-type: image/jpeg" );
    header( "Content-Disposition: inline; filename=" . $images[$x] );

    return $tehfile;

?>

Correct me if I'm wrong, but this code is not generally useful unless you have the ability to insert it where the avatar code is in vB and the files would need to reside on the server serving up the forum. :)

Correct -- I regularly visit 4+ other boards, which allow me to define a remotely-hosted image, so this comes in handy for me. As far as TFP is concerned, though, the code just looks pretty. ;)

Surely you can have the script pull the photos out from anywhere you want it to? Including remote HTTP hosts.

If you wanted to, but I would be careful about that -- many remote hosts will kick you in the pants if you remotely link their images.

I made some changes.... now it creates the image list automatically

PHP Code:
<?

    $path = "/home/wherever/your/files/are/located/";


    while($entryName = readdir($path)) {
      if (preg_match("(.jpg|.gif|.jpeg|.png)",$entryName)) { // the the current file is an image
        $images[] = $entryName; //get the file names
      }
    }
    closedir($path);

    $x = rand( 0, ( count( $images ) - 1 ) );

    $tehfile = readfile( $path . $images[$x] );

    header( "Content-type: image/jpeg" );
    header( "Content-Disposition: inline; filename=" . $images[$x] );

    return $tehfile;

?>

Here is one I use.

PHP Code:
<?php

  //Edit this line to the url of your image folder to randomize
  //Must be a relative URL in your server, do not put in a forward
  //or trailing slash for it to work.
  $url='photo/pics';
  //Stop editing, that is all. Call the image with <img src=url/filename.php> That's all, enjoy. :D

  $files=array();
  if ($handle=opendir("$url")) {
      while(false !== ($file = readdir($handle))) {  
        if ($file != "." && $file != "..") { 
        if(substr($file,-3)=='gif' || substr($file,-3)=='jpg' || substr($file,-3)=='png' || substr($file,-3)=='bmp') $files[count($files)] = $file;
        }
      } 
  }
  closedir($handle); 

  $random=rand(0,count($files)-1);
  if(substr($files[$random],-3)=='gif') header("Content-type: image/gif");
  elseif(substr($files[$random],-3)=='jpg') header("Content-type: image/jpeg");
  elseif(substr($files[$random],-3)=='png') header("Content-type: image/png");
  elseif(substr($files[$random],-3)=='bmp') header("Content-type: image/bmp");
  readfile("$url/$files[$random]");

?>
