Works really great, I love it!!!
Works great, even with picture tags! The fade-in effect of the lazyloaded images is really nice! And the developer is really active and helped me a lot! Thanks again, Patrick :)

Perfect
As a developer I knew the lib js that does a very good job. So I'm not surprised to have a plugin that does a good job too. (Except, video loading does not work)

It's perfect!!
I already tested some other plugins against this plugin for my site load speed and request counts. This plugin is greatly reducing my page load speed I really don't know why they couldn't beat this plugins performance on gtmetrix. Performance is really high as author mentioned!

Best Lazyload script on the planet
LazySizes is lazyloading done right. I've used it before and was pleased to see that it's now available as a WordPress plugin. For me, this is the best lazy-load script on the planet. I've tried many Wordpress plugins and all failed except LazySlides. Excellent!
