Random Image in Header

[yotoc]

First off, seems search is down and I've browsed through pages and pages and can't find an answer to this. 

I recently moved from phpbb to smf and am trying to put the random images I used in the header of my old forums to the new.  I was using a perl script but it won't seem to work with smf.

Anybody have any suggestions?

For a perl script its hard to make it actually work in SMF..but doing it in php is not so hard. What did the perl script essentially do?

It was pretty simple, not even sure why it was done in perl.  I just know it won't work with smf.

I figured I'd ask around here before going the php route.  Any idea how to do this?  If not, I'll work on it myself and just come crawling back here when I finally admit defeat.

no, I can help..what kind of images? how are they named? If they are named like xxx02.jpg its easier to setup a random function to generate a number..and simply display the image with that number in it.

If you have more categories/name styles, it can be done in 2 steps, first random category/name styles, then random image.

No, just 10 images.  logo1 through logo10.jpg

Make directory and put the images in it. Copy the code in your notepad and save it as index.php
Example of the code inaction:
**removed**
You can just add it as an image. Every load/reload the image changen to someting els.
Code for index.php:

Code Select Expand

<?php   

$handle = opendir('.');   
while (false !== ($file = readdir($handle))) {   
    if ($file != "." && $file != "..") {   
    $ext=substr($file,-4);  
    if ($ext == ".jpg" or $ext == ".gif" or $ext == ".png") {  
        $images[count($images)] = $file;   
    }  
    }   
}  
closedir($handle);   


srand((double)microtime()*1000000);  

$key = array_rand($images);  
$image = $images[$key];  
$ext=substr($image,-4);  

header("Cache-Control: no-cache, must-revalidate");           // HTTP/1.1 
header("Pragma: no-cache");  
header("Expires: Sat, 20 May 1995 03:32:38 GMT");  

if ($ext == ".jpg") {  
    header("Content-type: image/jpeg");  
}  
else if ($ext == ".gif") {  
    header("Content-type: image/gif");  
}  
else if ($ext == ".png") {  
    header("Content-type: image/png");  
}  

readfile($image);  
?>
