GotchaActually, bandwidth should be barely noticeable since each image is only about 8kb in size... so even all 5 of them (40kb) is about 1/5 as big as a regular photo you'd get from a friend... and about 1/1,000 as big as a short 20 second video from youtube, FB, etc.
Any slowness would be caused from the script trying to randomly pull from millions of images uploaded to the system.
