This image is empty with the data-src set

This one works! But shows the grey placeholder in webflow, which is what I'm wanting to avoid.

(data-src set in custom attributes on the image element)

This image is set in webflow with a data-src set to the same image as above.

This one doesn't work as the image in webflow is overriding the data-src attribute image. That's what I'm trying to "fix"/change.

It does show an image in webflow designer which is what I want.
