@Twansparent It’s certainly hard to decide whether a Repeater or a Custom post Type is the better approach. For an image gallery a Repeater is far more user friendly to edit, but if the Repeater grows too large I suspect performance and usability will suffer.
P.S. I realised that my custom function to generate pagination links is totally redundant since WP’s native paginate_links can be used instead. Facepalm. I’ve updated my blog post accordingly.
