attachment image height en width

[ageurtse]

I would like to know how to get an attachments height and width. how could i do this.

for displaying the image i use

PHP Code:

$output .= "<img border=0 src=attachment.php?attachmentid=".$post['attachmentid']."&thumb=1>"; 


i put this in a cel from a table. but i would scale the longest size to fit in this cell so it attachment would display normal and not stretcht out.


i think i use

PHP Code:

 if ($height < $width){$output .= "<img border=0 src=attachment.php?attachmentid=".$post['attachmentid']."&thumb=1 width=100%>";} 
else 
{$output .= "<img border=0 src=attachment.php?attachmentid=".$post['attachmentid']."&thumb=1 height=100%>";}; 


but how do i get this width and height

i have solved it myself, see the code below.

PHP Code:

function fetch_attachment_info($userid, $attachid, $thumb)
    {
        $image = fetch_attachment_path($userid, $attachid,$thumb,'');
        list($width, $height, $type, $attr) = getimagesize($image);

        if ($width<$height ){$scaleh=true;} else { $scaleh=false;}
        
        $attachinfo = array($width,$height,$scaleh);
        
        return $attachinfo ;
    }
?>

Where did you plug this info into to get this to work? In a template, in the attachment.php file???
