We have two concerns for passing the list of IDs. 1) The timeout problem. It happens unpredictable. If one failure, we lost all. Users hate to gain nothing after a period of waiting. 2) That request would be too long to wait. We hope that the images can be loaded asyncronously. So the page can show something as soon as possible. Plus, maybe I am wrong, 3) The client side ,even with Ajax feature, is hard to split the binary structure of list of Images and create the images from binary data. Maybe flash can do that, but it means we have to reconstruct the whole things, which brings another set of limitations and complexity. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
