How to display different images based on drawer ID in site-nav.liquid?

[SKSadmin]

Hello,

Any help on this would be great.

I am looking to add some code to my site-nav.liquid to show an image depening on the drawer ID.

If a customer click on "products" the drop down menu shows an images uploaded in files and if they click on "brands" it shows a different image from files. 

I cant seem to find the correct if and else to make it work. Sorry I'm new to Shopify.
