Assuming someone changes the image every 5 minutes, you'd cover 12/hour or 288/day. Would maintaining a FIFO queue of one day's worth of images be crazy big?

Assuming someone changes the image every 5 minutes, you'd cover 12/hour or 288/day. Would maintaining a FIFO queue of one day's worth of images be crazy big? I think it's reasonable to expect a person's computer to have internet access once a day to refill the queue.
