I have an image that send to affiliate for advertising. so, how can I find it out from my server the number of times that image been downloaded? does server log keep track of image upload count?

---- Addition ---- Thanks for the reply.. few more questions

because I want to do ads rotation, and tracking IP address, etc. so, i think I should do it by making a dynamic page (php) and return the proper images, right?

Bu durumda, ben sunucudan Google Analytics'e bu bilgileri gönderebilir yine de var mı? Ben javascript bunu biliyorum. ama şimdi, PHP bu yana sadece görüntüleri dosyayı iade edilmelidir. ben ne yapmalıyım? :)
