The first thing that I try after generating an image from DALL-E is using reverse image search. I do it on every image that I intend to use, more often than not, I find a very similar image, in this case I discard it and vary my prompts.
Can you give an example? I was also doing reverse image searches, and I havent seen a single case of an image being closely related to another unless it was used as the base for inpainting.
