Я новичок в написании сценариев. Я скопировал код отсюдаЗагрузить изображение в таблицу Google

Исходный сценарий позволял пользователю загружать 1 изображение через форму веб-приложения, а затем изображение добавлялось в строку в таблице Google и в Документ Google. Мне удалось изменить форму веб-приложения, чтобы позволить пользователю загрузить 2 изображения, но я не могу понять, как добавить второе изображение в электронную таблицу и документ.
