I noticed respimage advises to use a 'LQIP' while PictureFill advises to leave the `src` empty.\r\n\r\nCan you clarify the following?\r\n\r\n- Because of the browser Preloader we have double downloads in unsupporting browsers, running respimage.js. Correct?\r\n- ..it handles this intelligently using LQIP. But requires LQ images to be prepared?\r\n- What defines a LQ image? It is not, if I understand correctly, simply a 'small.jpg'...\r\n- What good would a data-uri'd 'blank.gif' do besides \"valid HTML\"?\r\n- What are the 'perf drawbacks' of an empty `src`?\r\n\r\nIn my situation I can not prepare LQ images (if that means re-compressing etc) so I went with an empty `src`. Now I wonder if I'm doing it wrong.\r\n\r\nTIA.\r\n\r\nPS: you are not on Twitter, right? FYI: I asked around there too: https://twitter.com/valuedstandards/status/579999578176503808\r\n\r\n\r\n"}}
