Hi,
In Gantry 5 we’re parsing menus in order to be able to utilise Gantry 5 features. If you want to use an image in the menu item all you need to do is to :
1. Click on the cog wheel next to the menu item in the Gantry 5 menu editor : https://monosnap.com/file/4kWViV8MXfb8ck9KCjLrvOBph96lXf.png
2. Paste URL (or use the picker) next to the Image field : https://monosnap.com/file/gsskA2MvVvXcir63xrZCfq7IDtOjp0.png
Thanks!
