Requested feature overview description.
Add necessary open graph meta tags.
Why would it be useful?
If someone is sharing the link to e6 post either on modern messaging applications, social media feeds or similar, most will show it as link only. If the site had proper data available, this would also show the user thumbnail, description and other small, but really convinient data.
This would also make it more viable to link post pages instead of direct url to images.
What part(s) of the site page(s) are affected?
At least post pages, but preferabely all sites publicly accessible pages.
