How to upload a jpeg image using custom liquid? (Beginner)

[dainex]

Hello!

I want to upload a JPEG image on my storefront inside a promo section, and i don't know how to do that.

I'm a beginner to the Liquid language and the docs is not helping me here.

The image is inside the Content Files folder in my Admin.

It has a URL Handle name of 'free_shipping_fast_truck'.

How can i use Custom liquid to load this image on my storefront?

Any ideas?

Sorry for being a beginner.
