Saving icons to database

Hi I want to make a navigation menu based on a repeating group. So that I can easily create a specific desktop and mobile menu which are always in sync. I want to have icons for each menu item. What is the best practice to save these icons. Just an small image or can I use something similar as the the icons in the icon element?

Maybe experiment with this to see if it will do the job: How to append an image to the end of a text element?

Hope that helps. :slight_smile:
