If I understood you correctly. you seent images that are just variations of a theme and I suggest that the moderator seelected one of them and rejected the rest as essentially "spam" - i.e., just variations of the same image. In the instructions to contriburors, we re specifically asked not to do this.
Adobe TOLD YOU the reason. Please tell us their rejection reason for each picture, so that we can suggest why this might have happened. Please don't make us guess.
