blog_post.cover_image.url(w: 800, h: 600, fm: :jpg)# => "https://www.datocms-assets.com/123/12345-heart.png?w=800&h=600&fm=jpg"blog_post.cover_image.lqip_data_url(w: 800, h: 600, fm: :jpg)# => "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wCEAAoHBwgHBgoICAgXFQoLDhUSDhUXDh0eDRUVGRYZGBYTFhUaIi0jGh0oHRUWJDUlKC0vMjIyGSI4PTcwPCsxMi8BCgsLDg0OHBAQHDsoIig7Lzs7Ozs7Ozs7LzsvLy8vLy8vLzsvLy8vLy8vLy8vLy8vLy8vLy8vLy8vLy8vLy8vL//AABEIAA0AGAMBIgACEQEDEQH/xAAYAAEAAwEAAAAAAAAAAAAAAAAAAwQFAv/EABwQAAAHAQEAAAAAAAAAAAAAAAABAgMEBRESQf/EABUBAQEAAAAAAAAAAAAAAAAAAAMB/8QAHREAAQMFAQAAAAAAAAAAAAAAAQAREgITITFCA//aAAwDAQACEQMRAD8AqPMJiF1o6jvlILkhlWU11aMMTU6j50UPHKcCmTJa1aXEnvoBdy3GmTNPgAwfTkpbNJ2F/9k="
