Update src on Image Machine

[K Series Parts]

Hi, I am testing something and need to update images from src to data-src. image machine keeps appending an src link rather than updating the data-src link. I am curious if anyone knows how to change the code from src to data-src because my attempts haven't worked.

Are you editing the PROD page,
then Product Display Layout Image Machine section
then Head Template
You can see how it builds the gallery using javascript.
It depends on the theme you're using of course.
But instead of it having something like
img.src = thumbnail_image;
you would change that to load a px.gif or whatever you're doing
and then add something like
img.setAttribute('data-src', thumbnail_image);
