question for you bandwidth people..
 

say theres a forum that goes through about 250,000 uniques a day has a huge archive of pictures that are available for everyone to check out. how much do you think bandwidth would cost for such a site per month?

Wow... I wouldn't be worrying as much about bandwidth as I would about the sheer server specs needed to run that powerhouse. Bandwidth is going to be high though depending on the quality/size of pics, anywhere from 5tb to 15tb of bandwidth a month. But sheesh, the server(s!) are going to have to be helluva powerful to handle that much traffic :| 174 uniques a minute is going to cause major damage.
