Currently the module fetches image-sources set as placeholder {image} as the raw max-size version of that image.
Adding max-width/max-height options for the og:image settings in the seo_maestro defaults could limit image sizes to e.g. 1200 x 630.
@esszett This feature is now available in version 0.7.0: You can configure a width and/or height of the opengraph image on field level to resize the image. Hope this makes sense, let me know otherwise!
