Question, what is the reason for rejection, too small a photo?

Same as the other one, yes. Larger sources were evidently available since you uploaded them quite quickly afterwards, so please make sure you upload the largest possible version in the first instance in the future.

And I've already asked you not to upload images as game ready in order to get around the request limit; please don't do that again. Use the upload response button only to upload a game-ready version for a requested source 👍
