Hi there,

There are two methods to do this:

Method 1.  To change that go to Laborator > Theme Options > Blog Settings and in the Thumbnail Height section change at what height you want the images to be cropped, then regenerate the thumbnails.

Method 2. Add the following code to your themes functions.php file to load the original image size.

function lab_blog_single_image_size_original( $size ) {
    return 'original';
}
add_filter( 'lab_blog_single_image_size', 'lab_blog_single_image_size_original', 100 );

Ahh, it seems I've missed the f character, have a great day
