This Moodle atto editor plugin provides a button to add a banner image to your course with the right styling. It has been developed for the FabLab Factory tutorials and activities.
Currently this plugin does not contain any behat tests yet. Feel free to contribute.

This plugin was based off the template for atto plugins by Justin Hunt https://github.com/justinhunt/moodle-atto_newtemplate
Additionally I used moodle-atto_image as a starting point for this plugin.
