Adding Image Sizes

As of GP Premium 1.10.0, we removed on-the-fly image sizing for featured images in our Blog module. WordPress itself has a hard time with this, and all of the available solutions have pretty significant downfalls.

By default, WordPress has a handful of image sizes to choose from:

• full – the full sized image
• large
• medium
• thumbnail

You can find these image sizes in Settings > Media.

It’s possible to create new image sizes specific to your site with a simple function. For example:

add_action( 'init', function() {
    add_image_size( 'my-archive-featured-image', 500, 200, true ); // 500 width, 200 height, crop
} );

Learn more about the available parameters here.

You can add more than one size at once:

add_action( 'init', function() {
    add_image_size( 'my-archive-featured-image', 500, 200, true ); // 500 width, 200 height, crop

    add_image_size( 'my-single-featured-image', 800, 500 );
} );

Once you’ve added your image sizes, you can choose them from the “Size” dropdown in Customize > Layout > Blog.

The last thing you need to do is regenerate your thumbnails. WordPress doesn’t do this by default, so it’s necessary to use a plugin like this.
