        $thumbnail['medium']['height'] = "150";
        $thumbnail['medium']['width'] = "150";
        if($imageprop['type']=="image/gif")
        {
            $thumbnail['small']['fullsize']= imagecreatefromgif('/home2/animati/public_html/dev/images/news/'.$newname.'');
            $thumbnail['medium']['fullsize']= imagecreatefromgif('/home2/animati/public_html/dev/images/news/'.$newname.'');
        }
        else if($imageprop['type']=="image/jpeg")
        {
            $thumbnail['small']['fullsize']= imagecreatefromjpeg('/home2/animati/public_html/dev/images/news/'.$newname.'');
            $thumbnail['medium']['fullsize']= imagecreatefromjpeg('/home2/animati/public_html/dev/images/news/'.$newname.'');
        }
        else if($imageprop['type']=="image/png")
        {
            $thumbnail['small']['fullsize']= imagecreatefrompng('/home2/animati/public_html/dev/images/news/'.$newname.'');
            $thumbnail['medium']['fullsize']= imagecreatefrompng('/home2/animati/public_html/dev/images/news/'.$newname.'');
        }
            $thumbnail['small']['canvas']= imagecreate($thumbnail['small']['width'], $thumbnail['small']['height']);
            $thumbnail['medium']['canvas']= imagecreate($thumbnail['medium']['width'], $thumbnail['medium']['height']);
            $thumbnail['small']['name']= "news".$articleid."_small.".$imageprop['extension']."";
            $thumbnail['medium']['name']= "news".$articleid."_medium.".$imageprop['extension']."";
            imagecopyresized($thumbnail['small']['canvas'], $thumbnail['small']['fullsize'], 0, 0, 0, 0, $thumbnail['small']['width'], $thumbnail['small']['height'], ImageSX($thumbnail['small']['fullsize']), ImageSY($thumbnail['small']['fullsize']));
            imagecopyresized($thumbnail['medium']['canvas'], $thumbnail['medium']['fullsize'], 0, 0, 0, 0, $thumbnail['medium']['width'], $thumbnail['medium']['height'], ImageSX($thumbnail['medium']['fullsize']), ImageSY($thumbnail['medium']['fullsize']));
        if($imageprop['type']=="image/gif")
        {
            imagegif($thumbnail['small']['canvas'], '/home2/animati/public_html/dev/images/news/'.$thumbnail[small][name].'');
            imagegif($thumbnail['medium']['canvas'], '/home2/animati/public_html/dev/images/news/'.$thumbnail[medium][name].'');
        }
        else if($imageprop['type']=="image/jpeg")

            imagejpeg($thumbnail['medium']['canvas'], '/home2/animati/public_html/dev/images/news/'.$thumbnail[medium][name].'');
        }
        else if($imageprop['type']=="image/png")
