Just did a quick test. Unfortunately, it seems that there is no built-in way to do it. If you want to have images in your navigation, you will need to use JS. You can search on the dev wiki to see if one already exists. If not, you can use the forums there to ask for help creating such a script. Although, I am not sure if such a change would constitute a violation of the customization policy. The wiki navigation is a gray area where you are allowed to make some changes but don't have free reign.
