I have a problem with set_post_thumbnail_size() function, which seems it doesn't work. Or at least it doesn't work correctly.
I have set a thumbnail size 75x75px in WordPress settings under the media section and have also set another thumbnail size in the functions.php using:
set_post_thumbnail_size(80, 80, true);
How are these two settings supposed to work? I believe the one that I set in the function.php (80x80px) should override the other in the media settings. Am I correct?
This is not the case though. Both sizes of the image exist in my uploads folder and what is worst I can't get the one I set with set_post_thumbnail_size() no matter what.
When I call
I get the one set in the media settings and not the one I set in my theme's functions.php. How can I get the other?
UPDATE: It seems I messed up 'thumbnail' and 'post-thumbnail'. In media settings I can set the thumbnail size, which is another image size as 'medium' and 'large'. Using set_post_thumbnail_size() I can set the post-thumbnail (aka featured image) size. Sorry for the mess and thanks for the answers.
