I’m trying to change the image wich is shown on the homepage, but only for the first post.
I want to change it from the thumbnail to the first image of the post.
What is the right function I can add a filter to?
I already tried ‘get_post_thumbnail’, but that didn’t work.
It should work automatically.
I’m not looking for a filter specifically for the first thumbnail on the homepage, but a filter for the thumbnail in general. Then I could limit my changes to this specific thumbnail via php.
Do you understand what I mean? 😉
