The actual scrolling of the image is handled by the browser, meaning that any performance problems remaining are caused by the browser itself.\r\n\r\nThe attached image is very large, and the web isn't known for handling large images quickly. I would recommend trying to go with a smaller image. That image would most likely be to large to see all at once on a mobile device anyway.\r\n\r\nYou can also try upgrading to Firefox 14, or switching to Safari/Chrome, both of which should be faster.",
