The QUESTION
I have seen several banners that have many pictures in it and all of them are clickable. Can you tell me how to put an ad like that? Also, I have seen a banner that is using gif (the word inside the image, can be changed regularly). Can we use gif image in our ads?
The ANSWER
This is a dynamic display ad that allows a website to dynamically display advertisements to users, based on products they have previously browsed on the website. In display ads, you can use whatever Google permits. So, yes you can use gif image.
