Help with resize image

[morningstar]

I wanted some help with bbcode, if someone post an image this bbcode do his job:

$bbcode = eregi_replace("\\[img\\]([^\\[]*)\\[/img\\]", do_image_post("\\1"),$bbcode); 

function do_image_post($link) { 
    $link = str_replace('\\"', '', $link); 
    $link = str_replace(' ', '%20', $link); 

/*
  $size = getimagesize($link); 

$height = $size[1]; 
  $width = $size[0]; 

$extra = ""; 
  if ($width > 400)  { 
        $width = 400; 
        $percent = ($size[0] / $width); 
        $height = ($size[1] / $percent); 

    $extra = "<br><a href=\"" . $link . "\"><b>See Image Full Size</b></a>"; 
} 

$link = "<img src=\"". $link ."\" border=\"0\" height=\"" . $height . "\" width=\"" . $width . "\" >". $extra; 
*/ 

$link = "<img src=\"" . $link . "\" border=\"0\" onLoad=\" if(this.width > 400) { this.width = 400; } \" >"; 
//                    onclick=\"if(this.width > 400) { window.open('".$link."','','scrollbars=1,toolbar=0,resizable=1,menubar=0,directories=0,status=0') } \" >"; 

return $link; 
}  

I saw that i cant request the imagelink because the php code will see the image link as \1 and not as a full image link.

So what i want to do is if the width is larger then 400 then resize the width to 400 (which work with the javascript though) and i wanted an image url right under the image that shows the full image in a blank window (that i dont get working also not in javascript)

How can i do this?

Have you looked at [man]imagecopyresampled/man ?

thnx for the response, no i didnt tryed that yet, i go do that now

//edit

hmm but that doesnt work also because it give an error at getimagesize($file),
it cant find the file because the file is yet : \1 and its not a full image link :bemused:

is it possible to search for all images in a text and then send all found images in the function and return the edited images in the text on the original place? instead of using the \1 with eregi..

thnx morningstar
