I load the images like this:- Image img = new Image(url); I don't want to use the ImageBundle because this is the point of the project...you only load images as the user scrolls up or down ..slow and fast etc.
I know about the paging toolbar solution but I need to implement this using scrolling. You can say this is my client's requirement (i.e the project's supervisor's requirement). The reason I am trying to do this is because it is new and hasn't really been seen in websites using AJAX. So is there no way I could find out which images of the flexTable the user can see? Thanks a lot for your help. Shivi On Apr 7, 6:44 pm, Arthur Kalmenson <arthur.k...@gmail.com> wrote: > How are you loading the images? Are you retrieving them from the > server one by one?
