Remove an Image when on preview and show on editor

Hey, @artf I need help with a challenge I've been facing

I want to hide images with src empty for particular class images in preview mode and show them on editor mode.

I've tried this but it doesn't seem to work for some reason

editor.on('run:preview', () => {
    $('.img[src=""]').hide();
});

editor.on('stop:preview', () => {
    $('.img[src=""]').show();
});

Thanks, Chaitu
