No image when user clicks like from facebook

We have checked your website, it seems that Facebook is properly sharing the image.

Please note that Facebook’s behavior is a bit different and it uses OG tags to crawl the pages and grab the data to be shared.
We only just pass the URL and then Facebook crawls the page to grab the data and on that we don’t have any control.
You can specify the Title, image, URL or description using the Meta tags.
For that you can use OG tags, like for sharing the Description you can use ‘og:description” and for URL you can use “og:url”
