I think there something different about a note that contains photos and a photo that contains notes. But UI needs improvement and maybe a lot of clients that do both should ask the user on first post and set a default.

I agree. I just realized that this is exactly what killed instagram.
one day someone realized that they can post a wall of text inside an image. a couple of months after, there are no normal photos, its just all memes and text walls hiding as images.
