when we share our url in a facebook post, there are two pictures shown as post pictures. We want to block one image (as it is a link to our partner) from being pulled by facebook. Does anyone know if, and when yes, how you can do that?
You will need advanced Open Graph plugin for that to control what shows up on FB. When you use a third party Open Graph plugin, you need to disable X Open Graph in Appearance > Customize > Social
