Website Screenshot Won't Work

Hey guys!

So I’m in the process of trying to embed a screenshot of another webpage into my site page. My site is thegrassrootsgarage.com. I’m currently trying to use the WP Screenshots plugin with the code [screenshot width=400]https://rateyourmusic.com/list/wbhyatt/the_best_albums_ive_ever_heard/8/[/screenshot] to generate my screenshot, but it doesn’t generate the website preview image.

Are there any other ways to embed the image of another website screenshot into my pages/posts?

Thanks!
