Parallax for One Image Only

Hello-- I'm trying to activate parallax scrolling for one banner image only on my site. This is a banner/background image set up as a Section on an Index page. The inspected code for the section is below, and I've highlighted the image url in bold. Thanks!

<section id="new-page-1" class="Index-page Index-page--has-image sqs-frontend-overlay-editor-widget-host" data-parallax-original-element="" data-collection-id="5de1a994a06c926920541ce2" data-parallax-id="5de1a994a06c926920541ce2" data-edit-main-image="Background">
