[code] Dynamic signature

[alphaest]

How the sig will look like, just look at my sig.

So that this thread wont grow to a helpdesk then people who dont know what php and ftp is should not try this code.

Needed:
- A accessible FTP server (public ones which have a webserver with php on it should do it prolly)
- PHP
- GD 2 or newer library in php (just see if the function imagecreatetruecolor works)
- header send - the public servers that put some crap in the head of the file or any other ad's and stuff arent suitable
- basic php knowledge

Code:

<?php
$path="data/";


$files=array();
$dirp = @opendir($path);
if ($dirp){
    $count = 0;
    while ($file_name = readdir($dirp))
    {
        if (($file_name != ".") && ($file_name != "..") && (!is_dir($path.$file_name)) && strpos($file_name,"_log")===false){
            $files[] = $path.$file_name;
            $count++;
        }
    }
    closedir($dirp);
}


$pic2 = $files[rand(0,count($files)-1)]; // take a random image from the list

header("Content-type: image/jpeg");


/////////////////////////////////////////////////////////////////////////////////////////////////////
$picsize=getimagesize($pic2);
$source_x = $picsize[0];
$source_y  = $picsize[1];


$kvaliteet = 85; // quality, dont use over 85, pointless

$maxw = 500; // maximum width for the sig, the image will be resized to this width
$crop = 150; // maximum height for the sig, image will be cropped from teh centre

$siz = $picsize;
if (($siz[0] > $maxw))
{
    $neww = $maxw;
    $x = $siz[0]/$maxw;
    $newh = $siz[1]/$x;

?>

sorry for the bad look of the code but it was just some file that got edited 1000 times for different purposes.


Images are located in ./data/ folder, waterm.gif is in the same folder.
Anyway, just look at the code and u'll get what its doing.
