check that the path in the code is the same as where you uploaded your images. By default IR creates a folder/directory titled "images". In your HTML code for the menu see that the path pointing to the images is correct. If the graphics are in the same directory as your HTML then they won't appear unless you change the code by removing the path to the image folder. Or make sure the graphics are in a folder called images.

slices are better than a single image map, sliced graphics load faster if size attributes are supplied in the code.
