For google ranking can google now find out and penalize you if you have duplicate content text in your images that can easily be found online. And the words I will be using will not be just few words but 1-2 sentences in a single image on the sale page. The sentence I will be putting in images (with blank white/black background and text color of red/green/black). So based on this information, can google penalize me for duplicate content text in your images which are really images of just sentence with no background of things of any kind.
