Progressive images for WordPress

This is a WordPress 🔌 plugin that loads your post thumbnail after your page loads.

Requirements

PHP > 5.3, since we use namespacing.

To install

• Download repo
• Move file to your wp-content/plugins directory
• Activate plugin via wp-cli or the WordPress dashboard

Issue reporting

I built this plugin for the 2017 Orange County WordCamp plugin contest, so I won't be actively maintaining this project.

Available filters

Remove functionality on ALL post thumbnails:

add_filter( 'Progressive_Images\enabled', function( $post_thumbnail_id ) {
    return false;
}, 10, 1 );

Remove functionality on a specific post thumbnail:

add_filter( 'Progressive_Images\enabled', function( $post_thumbnail_id ) {
    if ( 1234 !== $post_thumbnail_id ) {
        return true;
    }
    return false;
}, 10, 1 );

Add a class to the wrapping markup on post_thumbnails

add_filter( 'Progressive_Images\markup_wrapper_class', function( $class ) {
	$class .= ' your-awesome-class';
	return $class;
}, 10, 3);
