How to disable featured image loader

Hi!
In single posts page I hid the featured image with CSS like this:

.blazy.attachment-full.size-full.wp-post-image.b-loaded {
    display: none;
}

Still the blured placeholder is left when page is loading. What sould I do to remove it? I have made a chiled theme so I can modify php files.

Thanks a lot in advance
