A note on cropping: Each social network automatically crops images that do not exactly match their ideal image aspect ratio. For example, if you have a large image that is not in the 1.91:1 aspect ratio, Facebook may center and crop it to fit. Therefore, for maximum compatibility be sure that the most important parts of your images are horizontally centered.

How to Refresh the Preview Image Cache

After updating the preview image, if you try sharing your website link you will still see old preview content and image. That's because most social networks cache link preview content for at least a few days, if not weeks. You can use the official debugging tools provided by the social networks to reset this preview cache.
