 * Hello!
 * First of all, thanks for amazing plugin which just works.
 * I use litespeed cache plugin + Closte CDN which rewrites images URLs.
 * After installation and setup let me come up with advanced question.
 * I’m optimizing my site for speed and results are [here](https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fpetrenko.photos%2F&fbclid=IwAR2zKlEJHwrX8aRM1kKky-orfPyrayS3Y1Hdk9GlXq_dSeegzzH1foXkEjE).
 * One of the open points is “Serve images in next-gen formats” and it seems that
   something on the junction of CDN/litespeed/Visual Portfolio doesn’t work, not
   allowing viewers to see WEBP versions.
 * And second related question – why full size images are served to visitors even
   without clicking? Is it gallery feature?
 * Thanks in advance for suggestions.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fserving-webp-format%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hey.
 * I see all your images are in webp format.
 * Fullsize images may be loaded by lazyloading plugin automatically, based on srcset
   attribute:
 * [⌊srcset lazy loading⌉⌊srcset lazy loading⌉[
 * By default, our plugin generates automatically more image sizes and srcset attributes
   should contain it:
 * [⌊srcset lazy loading⌉⌊srcset lazy loading⌉[
 * Regards, nK.

 * Yes, I’ve posted in LiteSpeed plugin forum and they’ve suggested some ideas that
   helped.
 * I’ve switched off sizes that won’t be used to improve performance.

 * I recommend you add a little more sizes, because on some screens images loaded
   in low quality. For example, on the 4k screen, I see your images blurry.
 * These `srcset` images loaded only when needed and not on the page load, so I 
   don’t think you need to remove these sizes.
