I know how to change an image and text state for a mouse rollover. But what I'd like to do is change the background image of the website when the mouse is over one of the menu buttons. For example, when opening the site, the background is of a mountain, but when you rollover "about", the background changes to a river, when you rollover "shop", the background changes to a tree. Is there a way to do this without coding?
It is not possible to make by the standard means of the Muse. You should hire a web-programmer to develop this functionality.
