When we embed youtube videos on a page it calls for some URLs and it’s hard to get off to improve the score on page speed.
This plugin put an image thumb of the video with a play button instead of the youtube video. Simple and fast, just put a shortcode and it is working!
A CSS+JS solution using a Youtube automatic thumb or your hosted preferred thumb!
