in response to the request, providing a third tier of images to the client device as selectable replacements for the first tier of images in the respective scene.

14 . The method of claim 1 , wherein:

storing the second tier of images in the second image cache comprises storing duplicate images for respective images in the first tier; and

retrieving the second tier of images from the second image cache comprises retrieving the duplicate images.

15 . The method of claim 1 , wherein the personalized video is a personalized slideshow video.

16 . A server system, comprising:
