[BUGFIX] Add max width for social media images

The og:image and twitter:image meta tags are not resized.
If an editor puts a 5000 pixel wide image in a field,
it does not get resized, and if it is large
enough (in size + MB) it doesn't get picked up everywhere.

For this reason, we'll limit the image width to 2000
