I use Views Nivo Slider to rotate multiple imagefield content per node. Everything works fine and looks good when there are more than one image. However, sometimes some nodes on my website have only one image. In this case, a viewer's sight could bear with Direction Navigators on the edges of the image (still ugly), but that single ugly dot under image should ideally be hidden.

Unfortunately, css does not accept conditions, otherwise I could write a script checking if there are more than one images and if yes, then could play with 'div.view-node-image-slider' style.
