Pulling images form ACF field using dynamic data

Hi there,
I have come across this a couple of times and am not sure what I’m doing wrong.

I have an ACF group with about 15 fields, including 2 image fields.

I’ve then built a template pulling data dynamically into those fields using the dynamic data function. For all text and text area fields, I have no trouble but I seem unable to pull through images using the same methodology.

Are the parameters I’m using not correct for images?

Thanks!
