So I have a wordpress blog and when you post on Facebook it grabs the featured image as the Thumbnail for the post. But whenever I am doing this it is cropping all of thumbnails down so they look crappy, instead of resizing the image. Does anyone know how to fix this? I have searched and found facebook minimum is 200x200, well all of mine are above that but even square pictures such as 400x400 or 500x500 arent getting resized facebook is just cropping them off to make them smaller. Any help is appreciated!
