Rule Response: Add photo to field?

Hi,

I want the response for a rule to be… a predetermined photo is added to a file field.

Appears if you use set field values, it does not save the uploaded photo.

Can this be done, if so how?

I have not tested this, but I would try creating a Variable to hold the photo, then using the “Copy field values” rule instead, to copy from that Variable to the destination field.
