How do I add post authors’ signatures to the end of posts automatically and without a plugin? We can add them from the media library, but it would be very convenient to have them added automatically based on who is authoring a post.
I see that Advanced Custom Fields has a place for images. Is this a place to start?
you can use ACF to store a field against the user profile.
But you will probably need to create a shortcode to retrieve that image for now, as the GP/GB Dynamic data in the Image Block doesnt yet support that.
