I want to make a slideshow of pictures using iWeb. The things I want to do are the following:

1.) the show should start automatically when the user comes to the site.
2.) the show should be embedded in the site so that the users can't download the pictures
3.) the show should have forward and back buttons so that they can go back and forth if they see a photo for longer
4.) the show should continuously loop.

The problems I am having are that with iWeb, when you make a slideshow it puts all the photos on the site for you and then you have make a button for the slideshow and then it opens up some other window and you can control the back and forth motion. I don't want this, i want something like a movie that just starts when you go to the site and it has buttons.

Is this possible?
