Facebook not capturing the correct image on my post

See the AddToAny plugin’s FAQ on Facebook sharing, “For Facebook sharing, how can I set the thumbnail image and description Facebook uses?”

This plugin is managing your site’s Open Graph meta tags, so you’ll want to troubleshoot that plugin.

Too complicated for poor non-geek ! Why is this working fine with Google+ and Pinterest where you can select the image you want ? I prefer even Tumblr way allowing you to add a picture if you want (missing from others)…
Other similar plugin can do that, so it’s possible but I am unfortunately unable to propose any code (absolutely not a programmer) to help…
Your product is anyway very good, this is a minor but annoying problem…
