I am a little shocked at the lack of solidarity I see between artists working in different mediums wrt genAI.

they used stock art + Photoshop (or a free photo editor like Gimp or Paint or a cheap Photoshop clone like Affinity)

stock photos & illustrations from Deposit Photos ran me about 38 cents an image so even if I bought multiple images to "photobash" a unique cover then the cost was super low

admittedly i had some training in visual art but this stuff ain't rocket science, it just takes the willingness to experiment & train your eye as to what looks good / commercial in a cover image
