Random Avatar, PBV4 Compatability.

[MarvinRules]

Random Image

This requires a hosting service that supports PHP scripts. RipWay is a good free service that works with this.

Change this to the directory of your images. (DO not use the same directory that the index.php file is in)

This is the name of the PHP file itself.

All you need to do then place the URL to the PHP file in where you want the random image to be displayed. Place a bunch of images in your image directory, (Try to keep them all the same size if using for avatar or the like).

File Name "index.php"

<?php
$dir = "pics/";
$dh = opendir("$dir");
while (false !== ($file = readdir($dh)))
{
if (preg_match(('/\.gif/i'), $file) and $file != "index.php")
{
$filelist[] = "$dir$file";
}
elseif(preg_match(('/\.jpg/i'), $file) and $file != "index.php")
{
$filelist[] = "$dir$file";
}
elseif(preg_match(('/\.png/i'), $file) and $file != "index.php")

{
$filelist[] = "$dir$file";
}
}

srand((double)microtime()*1000000);
$picnum = rand(0, sizeof($filelist) - 1);

header("Location: " . $filelist[$picnum]);

closedir($dh);
?>

PBV4 Update!
The above code is not compatable with ProBoards V4. But with a few modifications you can get this to work with PBV4!

Modification #1:
You need a webhost that supports .HTACCESS files.
In the directory you have placed the above .PHP file you need to place a file that is called .HTACCESS. (This file is really a TXT file but without the .TXT at the end)
This file should contain the following:
AddType application/x-httpd-php .gif

Modification #2:
Rename index.php to index.gif
Now you just link to the index.gif the same way as the original instructions say to link to index.php.


OR all you have to do is put the index.php in a directory that ends in .GIF, .PNG, or .JJPG:
avatar.jpg\index.php

Then you do not need the HTACCESS file.

Your code could be a lot shorter then that. Look into groups with regular expressions.

Example:

if(preg_match("/\.(jpg|gif|png)/i", $file, $match)){
    // Match[0] would hold either "jpg", "gif", or "png"
}

The code started out as 2 seperate codes that I merged together. And I am not a pro coder by any means...

Soo, I will do some research and see what I can come up with.

You don't need to be a pro coder . Even i'm not a pro coder

[MarvinRules]

I never said that anybody shoud be, or has to be. I was just stating hoe inexperienced I am...

I have flubbed up my share of codes trying to modify them to do what I want... I have also added features to other codes that the original auther did not realize could be done.

I find it eaiser to modify existing code than to code from scratch... But that is me. And I am learning.

Or if you don't feel like doing that, or you are too lazy, PM me the URLs of the images you want to randomize and I'll make one for you
