Add image to taxonomy terms menu item My menu block is using the module: taxonomy menu terms to construct the main menu as a block to display in frontend.

I want to add image to each menu item, anyone know what is the simplest way to do that? or other module can do the same things?
Have you tried Menu Icons? It is useful. 
If you want to add some custom image to every term, add the field into your entity and upload default image. But I think, this module works better.
