Open Graph / Twitter cards

If you select an image for Open Graph or Twitter Cards <meta /> tags you can specify the dimensions of the image shared. You can change the width and height by TypoScript.

plugin.tx_yoastseo {
    settings {
        og.image.width = 640c
        og.image.height = 480c
        twitter.image.width = 640c
        twitter.image.height = 480c
    }
}

Set different fallback images for each site

There is a settings panel which you can use to set fallback images for opengraph and Twitter. These will then be used for your site. If you have multiple sites however, there is a need to set different fallback images for each site. This is possible by using the opengraph and Twitter image fields on the root page of each respective site. You can then use the following TypoScript to use those images as fallback images:

lib.yoastSEO {
    og {
        fallBackImages {
            references {
                fieldName = og_image
            }
        }
    }
    twitter {
        fallBackImages {
            references {
                fieldName = twitter_image
            }
        }
    }
}
