Yeah, I personally don't think it's great for licensing images as stock photography. The pricing could get weird and controlling the terms (or price based on terms) isn't really available so for now, that's a no for me.
But, if someone wants a "collectable", I can see the value in an nft "product", IF everyone plays by the rules. (I look it as kind of like a cool expensive splinterlands card that you never actually use in battle.) It will be interesting to see how abuses and solutions evolve. For now, I'll offer an image or two while I learn more...
