Image not showing up in social share

When I share a link to my website, there are no images in the Facebook share post. I looked in the Facebook URL linter and it shows me that the site is generating the OG:image tag. Any one have a solution for this? tx

I'm also having this issue - is someone able to assist?

Make sure you have uploaded an image on your home page settings,  or if you have one, your landing page settings, in the  social media setting, in social media preview image field and alternate social media image field. It would also be a good idea to put one in Media banner thumbnail image field as well. 

I'm having the same issue but it's on and off. All my social images are set. I shared and it included an image. Then the next day I viewed the post and no images were shown. I didn't change anything but the image was gone on Facebook and LinkedIn and thus the post has essentially died. LinkedIn inspector says No Image Found and says to include this code... <meta name="image" property="og:image" content="[Image URL here]"> is that valid?
