Yes, exactly. When a client supports both kind 1 and kind 20, it can easily confuse users, and it's hard to handle because, from their perspective, the difference between the two isn't that significant.

As of now, I don't see the need for adding a new type to distinguish image-based notes. I also don't understand why Olas is doing it this way, it could easily achieve the same result with a special tag, like ["c", "image"]
