is there anything similar available for vb 4?

Stopped working, not showing the images.

Going to disable it now.

Right click on one of those broken images and look at the URL it's looking for for the images.

how would we go about changing the image type from jpg to png or gif, i have tried changing jpg inside the product file and the show.php and having my folder full of nothing but png's
(did the same with gif's) but it just gives me an infinate load when i try to go to my register page.

EDIT*
after reading a little about the whole GD rendering from
http://www.php.net/manual/en/function.imagepng.php

i tried changing my show php to:

PHP Code:


		
			
session_start();
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

require_once('./global.php');
$percent = $vbulletin->options['eic_imgsize'] / 100;
$d = dir($vbulletin->options['eic_imgpath']);
while (false !== ($entry = $d->read())) 
    if (substr($entry,-4) == '.png')
        $answers[] .= $entry; 
$image = $_SESSION['show_images'][$_SERVER['QUERY_STRING']-1];
$im = imagecreatefrompng($vbulletin->options['eic_imgpath'].'/'.$answers[$image-1]);

list($width, $height) = getimagesize($vbulletin->options['eic_imgpath'].'/'.$answers[$image-1]);
$newwidth = $width * $percent;
$newheight = $height * $percent;
$thumb = imagecreatetruecolor($newwidth, $newheight);
imagecopyresized($thumb, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

header("Content-type: image/png");
imagepng($im);
imagedestroy($im);

i thought that would do it, but seems to still give me an infinate load.

also, this version is new than the one posted in the 3.8 section correct?

Before anyone absolutely kills me for not having supported this over the past few years, my forum was hacked, wiped completely clean (including database) and then I just gave up, but have been prompted to restart what I had achieved, so I've managed to recover my user for which I'd lost the password and email account.

I've just tried installing this on VB 3.8.4 and it works great. I haven't have opportunity to read through all the comments but will reply wherever I need to.

I shall now work to incorporate the built-in 5 strike 15 minute feature to aid protection from bots.

I also have a lot better understanding of the coding now and MySQL so hopefully this will help to evolve the plugin.
