I was wondering if I can change Image Size option in the post settings panel. From Large to Full Size. Automatically in all posts? I have about 500 posts... :) Seem can not find any answer to that. Thank you!

Here is the screenshot

  • I don't think there is a way to bulk update like this. Do you want to change every image or just the first in a post? Are you familiar with PHP programming in WordPress?

Well, i think you totally right, there is no way to bulk change like that. But i found solution. Since Google Discover uses Featured Images for display, i can add my big size Featured Image to the post <?php the_post_thumbnail('full'); ?> and hide it with css from the page rendering, but Google will use it as a display image.
