Hello Jason,
Thanks for writing in!
I went ahead and made the necessary changes in your site to make the featured images as square. I did the following:
1.) First, I added this custom PHP code in your child theme’s functions.php file in Appearance > Themes Editor:
// Square Featured Image
// =============================================================================
//
//
add_image_size( 'squared', 450, 450, true );
//
// Output featured image in an <a> tag on index pages and a <div> for single
// posts and pages.
//
if ( ! function_exists( 'x_featured_image' ) ) :
function x_featured_image( $cropped = '' ) {
$stack = x_get_stack();
$fullwidth = ( in_array( 'x-full-width-active', get_body_class() ) ) ? true : false;
if ( has_post_thumbnail() ) {
$thumb = get_the_post_thumbnail( NULL, 'squared', NULL );
switch ( is_singular() ) {
case true:
printf( '<div class="entry-thumb">%s</div>', $thumb );
break;
case false:
printf( '<a href="%1$s" class="entry-thumb" title="%2$s">%3$s</a>',
esc_url( get_permalink() ),
esc_attr( sprintf( __( 'Permalink to: "%s"', '__x__' ), the_title_attribute( 'echo=0' ) ) ),
$thumb
);
break;
}
}
}
endif;
2.) I installed a 3rd party plugin, Regenerate Thumbnails and then I have regenerated the thumbnails so that a Squared Image is generated for the featured image.
