I want to select an image for OG Meta / FaceBook – Not feature image

Does anyone know of a plugin where, on the post page, you can select an image for sharing. It’s taking the featured image which is not are right size. I’d rather create a new image for sharing. Is there a plugin that will allow me to select a specific image for OG Meta for each post??? I can’t seem to find one 🙁 HELP!!
