Yes, I’ve tried all that. Even in different installations of WP.

Could you show me a screen capture of your configuration page? Just to be sure that I’m the one having the problem.

Anything?

Yes, its setup looks just like that in my functions.php file:

function my_thumb_sizes() {
	add_image_size( 'large', 620, '', array( 'center', 'center' ) ); // Large Thumbnail
	add_image_size( 'medium', 300, 300, array( 'center', 'center' ) ); // Medium Thumbnail
	add_image_size( 'thumbnail', 160, 160, true); // Thumbnail
	add_image_size( 'custom-size-1', 320, 160, true); // Custom size 1
	add_image_size( 'custom-size-2', 620, 320, true); // Custom size 2
}

add_action( 'after_setup_theme', 'my_thumb_sizes' );

That’s the problem. I don’t have them, and I don’t know why :S Everything I can see is what I showed you in the picture above.

I tried everything you suggested, but it’s still not working. Does the medium and large sizes allow you to crop them?

Something I discovered is that it works fine for custom image sizes.

Here goes my config:
IMAGE

I’m not completely sure what you mean with programmatic changes, but this is how I coded the image sizes in my theme:

add_image_size( 'large', 620, '', true); // Large Thumbnail
add_image_size( 'medium', 300, 300, true); // Medium Thumbnail
add_image_size( 'thumbnail', 160, 160, true); // Thumbnail

Is there anything else I should do so your plugin allows the cropping feature for medium and large sizes? Because, as you can see, the medium size is already being cropped by default, but when I activate your plugin, it doesn’t work anymore, WP will just resize them without cropping them.

I don’t see any cropping options for medium and large sizes. Only for thumbnail size. Could you give me more details about this?

So is there a way to get medium and large sizes cropped just like with thumb size?
