Answer 1

/*Path to Images folder*/
$dir = WWW_ROOT . 'img' .DS. 'thumbnail';
/*Explode the name and ext*/
                $f = explode('.',$data['image']['name']);
                 $ext = '.'.end($f);
    /*Generate a Name in my case i use ID  & slug*/
                $filename = strtolower($id."-".$slug);

     /*Associate the name to the extension  */
                $image = $filename.$ext;


/*Initialize you object and update you table in my case videos*/
                $Videos->image = $image;     
            if ($this->Videos->save($Videos)) {
/*Save image in the thumbnail folders and replace if exist */
            move_uploaded_file($data['image']['tmp_name'],$dir.DS.$filename.'_o'.$ext);

            unlink($dir.DS.$filename.'_o'.$ext);
                }
