SharePoint 2010 / jQuery - Swapping Images

By
Web part uploaded and forgot to include the image in the feature? This could be a potential issue on a managed SharePoint 2010 environment (Office 365 - Dedicated, etc.). The reference points to a path in the _layouts folder. How can I temporarily resolve this issue until I update the project?

  jQuery('img[src="/_layouts/images/old-image.png"]')
    .attr("src", "/subsite/PublishingImages/new-image.gif");
});
