Now as a guess, I could come up with several reasons for the application. One is that the format for the image data is not supported by normal browsers and they use an application to retrieve and handle it. It puts all the work on your machine and not theirs. A Java applet may do the same job but then they would have to serve the applet to every user every time they are accessed. That can run into a huge server load when things are popular. Of course, running Java on top of your operation system is not that efficient since it goes through several layers of programming like from your browser to the Java engine to your OS to actual machine instructions. That might annoy the user by slowing things down if you are doing something intensive like rendering a 3-D object. All of this is just reasons I can see for using a downloaded application. SNAFU |
