Thumbnail sizes

Hi @bithons!
The better way to change thumbnail sizes is create your own child theme for Azeria. Then add to your child theme file functions.php with next code:

<?php
add_filter( 'azeria_image_sizes', 'azeria_child_image_sizes' );
function azeria_child_image_sizes( $sizes ) {

	$sizes['post-thumbnail'] = array(
		'width'  => 850,
		'height' => 400,
		'crop'   => true
	);

	return $sizes;
}

This sizes will be applied for all new images. To change size of existing images – you need to use Regenerate Thumbnails plugin. We checked this code with exactly the same size image as you describe – all works fine.

Child themes tutorial you can find here

Thanks for you reply it worked, and the Regenereate Thumbnails is a handy one. And I am using a child-theme now.

I used this code for setting more image size settings, for people who maybe don’t know how to do it.

$sizes = array(
		'post-thumbnail' => array(
			'width'  => 850,
			'height' => 450,
			'crop'   => true
		),
		'slider-thumbnail' => array(
			'width'  => 1204,
			'height' => 900,
			'crop'   => true
		),
		'related-thumbnail' => array(
			'width'  => 210,
			'height' => 180,
			'crop'   => false
		)
	);

	return $sizes;
}
