The official description of this is: "Expand creativity and tell bigger stories through images of any size generated by DALL·E." The reason to try this product was due to seeing an interesting set of pictures online:
Therefore, I also tried using DALL·E. Just submit a picture, input some keywords, and then let DALL·E start creating.

Nevertheless, this product is still in the demonstration phase, and there is still a distance to go before it can be truly commercialized and productized.
