I have a static web page would has to be very long horizontally for display a se开发者_如何转开发quence of images and text. (around 50000x1024 pixels in whole).

Would like to ask what is the easiest way to make a "always on top" navigator, which display a small thumbnail of the whole web page. When a user clicks on the thumbnail, the web page will scroll accordingly.
