Have you read this thread: http://forums.digitalpoint.com/showthread.php?t=18917 ? You won't get many clicks but alot of impressions but people now get paid for impressions (not much)
I've actually gotten a couple of surprising clicks here. Definitely not $0.03 clicks, although you're still not going to make $$$ on it.
Picture ads displayed while you're going through the page. Publisher get money even nobody looks or clicks at them.
