2 questions! If category = id post thumbnail size is =? and Facebook api

BUMP

read this for the thumbnail size question: https://codex.www.ads-software.com/Function_Reference/add_image_size

this in your theme’s functions.php:

if ( function_exists( 'add_image_size' ) ) {
	add_image_size( 'category-thumb', 300, 9999 );
}

and this in your theme’s template files (inside the loop):

if ( has_post_thumbnail() ) {
  if (is_category('3')){
  the_post_thumbnail( 'category-thumb' );
  }
}

Thank you very much keesiemeijer! ??

You’re welcome. I’m not on facebook so I can’t answer that one. Maybe ask their forums?
