How to make your new Facebook Share Image Show

If you have set an image for your page to use when it is shared on Facebook, sometimes Facebook will not show the image when you test out the sharing feature. This is because Facebook stores a cache (temporary memory) of your page, so you need to refresh this memory in order for your new image to show.

To do this, go to the Facebook URL Debug Tool:
https://developers.facebook.com/tools/debug

Enter your page URL there and click "lint" and this should refresh the page data.
