I think this should work: $attachments = get_children( array(‘post_parent’ => get_the_ID(), ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’) ); if ( $attachments ) { // do conditional stuff here }
You have to write custom code to get the attachment id and post_parent by name/ slug or filename(if it has not been changed during the uploading of files). Put the below code in your theme’s functions.php file if( ! ( function_exists( ‘wp_get_attachment_by_post_name’ ) ) ) { function wp_get_attachment_by_post_name( $post_name ) { $args = array( ‘posts_per_page’ … Read more

Use the jpeg_quality and wp_editor_set_quality filters to set the quality of resized images: add_filter( ‘wp_editor_set_quality’, ‘wpse246186_image_quality’ ); add_filter( ‘jpeg_quality’, ‘wpse246186_image_quality’ ); function wpse246186_image_quality( $quality ) { return 100; // 0 – 100% quality } I have not been able to reproduce the issue reported; the original PNG image looks the same as the thumbnails.

Some suggestions: If you want to try out the Image Editor API you can try to replace imagejpeg( $resource, $image, 35 ); with: $editor = wp_get_image_editor( $image ); if ( ! is_wp_error( $editor ) ) { $editor->set_quality( 35 ); $editor->save( $image ); } unset( $editor ); Also try to test e.g. these parts: $resource = … Read more
