I don't have any pictures but I've been inside the older houses (Barnes, Burke) before. They're your standard res hall, most rooms are shared between 2 people, maybe 10-15 rooms a floor with a common room and a couple of bathrooms. Old res buildings have about 100 people in total. It isn't luxury but it isn't also poverty.
As for the newer res buildings, east and west tower, they're huge, with about 500 or so people in each tower. Brand new buildings, they're reallll nice. Private rooms in almost an "apartment like setting" with two (or maybe even 3) people sharing an apartment, with a bathroom in each. Much more private, also has common rooms and such. But I think you have to pay a higher price to stay here.
EDIT: The exterior of the res houses are probably the best feature of campus.

DOUBLE EDIT: found a (small) picture of what the regular room in the older res houses looks like.
