post_thumbnails_divi.php is where Elegant Themes‘ Divi specifies the custom image sizes:
add_theme_support( 'post-thumbnails' ); global $et_theme_image_sizes; $et_theme_image_sizes = array( '400x250' => 'et-pb-post-main-image', '1080x675' => 'et-pb-post-main-image-fullwidth', '400x284' => 'et-pb-portfolio-image', '510x382' => 'et-pb-portfolio-module-image', '1080x9999' => 'et-pb-portfolio-image-single', '400x516' => 'et-pb-gallery-module-image-portrait', '2880x1800' => 'et-pb-post-main-image-fullwidth-large', ); $et_theme_image_sizes = apply_filters( 'et_theme_image_sizes', $et_theme_image_sizes ); $crop = apply_filters( 'et_post_thumbnails_crop', true ); if ( is_array( $et_theme_image_sizes ) ){ foreach ( $et_theme_image_sizes as $image_size_dimensions => $image_size_name ){ $dimensions = explode( 'x', $image_size_dimensions ); if ( in_array( $image_size_name, array( 'et-pb-portfolio-image-single' ) ) ) $crop = false; add_image_size( $image_size_name, $dimensions[0], $dimensions[1], $crop ); $crop = apply_filters( 'et_post_thumbnails_crop', true ); } }
I wanted to modify the “et-pb-gallery-module-image-portrait” thumbnail size to be 500×500. Since I was using a child theme, my thought was to copy the post_thumbnails_divi.php into the child theme and change the value there.
…Nope, that didn’t work.
