Welcome to the second part of a two-part series that explains how to set up a three-dimensional HTML image gallery using Active Client Pages (ACP). In this part of the series, among other things, we'll get a close look at the JavaScript that helps to keep things running smoothly.
Completing an ACP 3D HTML Table Image Gallery - User Viewing the Gallery for the Second Time (Page 4 of 4 )
It may be possible that the user might have seen the gallery yesterday and today he wants to open the page and go straight to a particular image in the second plane. So, as soon as the page is opened, he clicks the button to reach the second plane, but to his amazement, after all the noise we've made about increased speed with ACP, he does not see the images of the second plane, because the images have not yet been downloaded.
The second set of images is supposed to be downloaded while he is seeing the first set of images. In this case, however, he did not spend any time on viewing the first set of images. Well, this situation can arise, but the probability that it would arise is small, for the following reasons:
Images galleries are usually arranged in order, so that you see the first set of images before you see the next set, then the next set, and so on; or you see the first image, then the next one, then the next, and so on.
In a gallery, the user would hardly ever memorize the particular position of a particular image. There are usually many images. So a user may vaguely remember what and where the image was. So he or she would still have to follow the order in which the images are arranged to get to the image in question. In this case, the user may not spend too much time with the preceding set of images, but would still spend some time. The next set of images are downloaded in whatever time is spent looking at the first set; this would still give the impression of fast operation.
