Image upload & re-size
 
I'm using the following code to upload & re-size images. However it isn't resizing them. Any ideas?

PHP Code:
    require_once(DIR . '/includes/class_upload.php');
    require_once(DIR . '/includes/class_image.php');

    $upload = new vB_Upload_Image($vbulletin);
    $upload->image =& vB_Image::fetch_library($vbulletin);
    $upload->path = $vbulletin->GPC['imagespath'];
    $upload->maxwidth = 120;
    $upload->maxheight = 120;
    $imagepath = $upload->process_upload($vbulletin->GPC['upload'])); 
Thanks,

Was same problem https://vborg.vbsupport.ru/showthread.php?t=220191
And i found that class vB_Upload_Image is not complete, as stated in the documentation http://members.vbulletin.com/api/vBu...oad_Image.html
Original look
PHP Code:
class vB_Upload_Image extends vB_Upload_Abstract
{
    /**

        }

        }

        @fclose($fp);

    }
} 
judging by the other classes.
Now $upload->maxwidth and $upload->maxheight works :)
