This can probably best be achieved with an _opengraph parser_ of some sort.

It'd replicate the existing functionality of both _Reddit_ and _Prismo_:

This is something I'd like to take a poll on before adding.

Vote here.

Sites like hacker news, and lobste.rs, don't have image previews, and it does makem look pretty clean:

This should be a toggleable feature.
That the user and/or admin can decide whether or not this feature is enabled.

Definitely should be optional, and definitely a low priority issue right now.

I relented and added image thumbnails at least. It only works if your url is an actual image tho.
