do you have an idea how to make menu with pictures representing tabs?

I need to build website with submenu which is not a standard menu but just a set of pictures on the website.
When you click on the picture you should be taken to the specific page of your websites.

Or you can use the I18N Custom Fields plugin with a custom field 'image' and then use custom navigation rendering with the I18N plugin using this 'image'.
