MenuIcons

This module allows you to upload an image in the menu-item's configuration form.

After uploading the image, the icon data will be added to the menu link's
options array.

When a menu link is goes through the theme layer, it will receive an extra
class which by default is used to attach the images as a background image to the
corresponding menu item. These class names are also compatible with Nice Menu's.

In the near future we will provide usage of inline images as an optional
feature.

When Imagecache is installed, you can choose an imagecache preset for uploaded images.

A screenshot of the menu-edit form with menu_icons enabled is located here.

This is Drupal 8 port of https://drupal.org/project/menu_icons module.
