Hi @stevenharris
Currently, your data setup is showing 1 artwork per page. Another way to do this would be to use the repeater field to add multiple images to 1 artist page.
Hopefully, ‘artist’ is a post type and you can then create 1 artist called ‘John’ and his images to his post through the repeater field.
Then on the template, you could render out these images however you want. Perhaps a gallery, slider, lightbox?
Does this help?
Thanks
