      i will give you an example ,suppose i am displaying the image ad using <img> object,my next ad to display is flash means i will create <embed> object and i am using repalcechild() to replace current ad with new one.and it will go in loop.
     i am receiving this error message if i run it for continuously more than 12 hours -     "your system virtual memory is too low,windows is increasing the size of the virtual memory paging file ,during this process memory request for some application may be denied". 

        my request is is there any common object   that will display image,text ,movie and flash files .i am new to this javascript field.tnxs for reply

      Suresh,

  It sounds like for some reason you are creating image objects all the time and they are not being garbage collected.  Truth be told, browsers are not really designed to do this sort of thing, so even if your code is theoretically correct, you might have to ‘help it along’ a bit to get the browser to behave properly.

  I would suggest that you use one image and cycle its src attribute instead.

  To do the preload, again use one image object which is not actually displayed and cycle its src until all are in the cache.  The browser cache is at the url level not the object level, so there is no requirement to store image objects for the data they contain to be cached.

  Hope it helps.

    Hi,

       I am facing one problem in my project.i am working in myadtv project that will display ads one by one in big LCD screen .

      suppose if i want  display 100 ads one by one  for a particular duration,after displaying the 100 th ad again it will start from 1 ad and goes in a loop until the user closes the browser.

     my problem is  ,if its runs  for continuously more than 10 hours if am displaying the message as 

                         " your system virtual memory is too low,windows is increasing the size of the virtual memory paging file ,during this process memory request for some application may be denied".    i can't understand this error message ,can any one tell me what this errror  message.

                      the logc behind our code  -   we are using javascript "imagepreloader()  function to load the ads in the browser cache once it gets loaded then it will start displaying one by one.
