add image size still doesn’t work even after regenerating thumbnails

by

I’m encountering this very frustrating problem where add_image_size() just doesn’t seem to work at all (in fact, I’ve never seen it even work before). By not working, I mean not resizing / crop (if I take away my CSS width / height, the thumbnail will be the exact size in which I have uploaded it).

I do have:

  1. add_theme_support( 'post-thumbnails' )
  2. add_image_size( 'small-thumb', 60, 60, true )
  3. the_post_thumbnail( 'small-thumb' )
  4. And most importantly, yes I’ve been regenerating my thumbnails close to 50 times now after changing the add_image_size() and it’s not working.

Now I do have a question related to this problem: Does CSS styling like max-width/ max-height/ width / height or anything effect WordPress’ thumbnail functions?

Anyone seem to know what else I can try to fix this?

Thanks

There are a couple of things to check here.

First, make sure that add_theme_support( 'post-thumbnails' ) is loaded before add_image_size( 'small-thumb', 60, 60, true )

You can always hook everything through a function to the after_setup_theme hook. I always add these in my theme setup function

function wpse_setup_theme() {
   add_theme_support( 'post-thumbnails' );
   add_image_size( 'small-thumb', 60, 60, true );
}

add_action( 'after_setup_theme', 'wpse_setup_theme' );

Apart from that, everything should work if you call your post thumbnail correctly in the loop.

On your question

Does CSS styling like max-width/ max-height/ width / height or
anything effect WordPress’ thumbnail functions?

No, it doesn’t. CSS only manipulate how a thumbnail is displayed on the front end
