Hello,

Sorry for the late reply.
In your functions.php file you can see these lines of code:

function codeless_images_sizes(){
    
    add_image_size( 'port3', 600, 600, true );
    add_image_size( 'port3_grayscale', 627, 470, true );
    add_image_size( 'port2', 460, 275, true );
    add_image_size( 'port2_grayscale', 940, 470, true );
    add_image_size( 'port4', 600, 600, true );

    add_image_size( 'blog', 825, 340, true );
    add_image_size( 'alternate_blog', 440, 195, true );
    add_image_size( 'alternate_blog_side', 355, 235, true );
    add_image_size( 'blog_grid', 350, 350, true );

    add_image_size( 'staff', 400, 270, true );
    add_image_size( 'staff_full', 500, 340, true );

}

Here you can edit or add the default image size cropping. Example, the images of two column grayscale portfolio will automatically be cropped to 940 x 470px as set in this line: add_image_size( 'port2_grayscale', 940, 470, true ); Change the values to your need, or add more types if you want. Make sure to import images again after editing and run a plugin to recreate thumbnails.
Let us know if you need help.

Best regards!
