Co-Authors Plus replaces WordPress's single-author model with a taxonomy-backed multi-author setup. Each post has any number of authors stored as terms in the author taxonomy, with guest authors (people without a WordPress account) stored as the guest-author custom post type. The plugin exposes a clean API for fetching the resolved co-author list on any post.

Default OG generators only ever see the single primary post_author field. So an investigative essay co-written by three journalists shares as if only one of them wrote it, even though the post itself proudly bylines all three. The credibility math that drove the editor to set up Co-Authors Plus in the first place gets stripped at the moment of sharing.

SleekPixel reads the co-author taxonomy and the guest-author CPT, resolves each co-author to a name, role, and avatar, then renders a per-post OG image that bylines every contributor. Two-byline posts get a side-by-side credit. Three-byline and larger posts get a stacked credit with the primary on top. Guest authors render with the same visual weight as WordPress-account authors, the way Co-Authors Plus intends.

Co-Authors Plus exists because credit matters. When two or three writers collaborate on an investigation, an essay, or a tutorial, the byline does real work: it tells readers who to trust, it grows each author's individual reputation, and it recruits future shares through each author's network. The default WordPress OG image strips all of that and credits only the post_author database field.

A SleekPixel card that renders every byline restores the credit and turns the share into recruitment for every contributor's audience. The fields are already maintained by Co-Authors Plus. The author taxonomy, the guest-author CPT, and the resolved co-author API are all there.

SleekPixel reads what the plugin already writes and regenerates the OG image whenever a byline changes. For an editorial site that runs forty multi-byline pieces a quarter, that is dozens of refreshed previews keeping the credit accurate across every share channel.
