I've setup 8 image ads and have over 1000+ keywords in my campaign. For the past 5 days there seem to be no traffic. Do you know why?
no traffic (clicks)? are you getting impressions? If you are getting impressions then your campaign is active otherwise your campaign is under manual review. As google professionals manually check Image ads before approval.
Image ads always take longer to be reviewed - typically 2 or 3 days, and they don't do it over the weekend.
