    /**
     * Write code on Method
     *

        $image_parts = explode(";base64,", $request->signed);
              
        $image_type_aux = explode("image/", $image_parts[0]);
           
        $image_type = $image_type_aux[1];
           
        $image_base64 = base64_decode($image_parts[1]);
           
        $file = $folderPath . uniqid() . '.'.$image_type;
        file_put_contents($file, $image_base64);
