vb.org Archive - auto image size adjustment

I got this hack from another thread, can't find the link, but I had it saved to my hard drive.

It adjusts all images that are posted using the [img] tag to a size of 400.

I was hoping somebody could help me tweak this hack.

in /forums/admin/function.php

find

PHP Code:


		
			


if($dobbimagecode and ($bbuserinfo[userid]==0 or $bbuserinfo[showimages])) {

      // do [ img]xxx[ /img]

      $bbcode = preg_replace("/(\[)(img)(])(\r\n)*([^\"".iif($allowdynimg,"","\?\&")."]*)(\[\/img\])/siU", "<img src=\"\\5\" 



border=\"0\" alt=\"\">", $bbcode);

    }

replace with

PHP Code:


		
			


if($dobbimagecode and ($bbuserinfo[userid]==0 or $bbuserinfo[showimages])) {

      // do [ img]xxx[ /img]

              $thispic=explode('[img]',$bbcode);

        $thispic1=explode('[/img]',$thispic[1]);

        if ($thispic1[0] != ""){

        $size = GetImageSize("$thispic1[0]");

        }

        if ($size[0] >= 400){

             $bbcode = preg_replace("/(\[)(img)(])(\r\n)*([^\"".iif($allowdynimg,"","\?\&")."]*)(\[\/img\])/siU", "<img 



src=\"\\5\" border=\"0\" width=400 alt=\"\">", $bbcode);



           }else{

             $bbcode = preg_replace("/(\[)(img)(])(\r\n)*([^\"".iif($allowdynimg,"","\?\&")."]*)(\[\/img\])/siU", "<img 



src=\"\\5\" border=\"0\" alt=\"\">", $bbcode);



           }



    }

NOTE: I had to put a space in the image tags "[ img]xxx[ /img]"

The part that I would like help with is getting is so that the image automatically makes itself clickable to see the full version. Can somebody please help me out with this?

I was also wondering if something like this could also be implemented to the attach feature, so that if somebody attaches an image into a post it does the same thing, where it's small and clickable for the larger version?

If somebody could please help me, I would greatly appreciate it.

Thanks for any help you can offer. :(
