Image updates are not being seen after deployment

I have a site published to Netlify and working well, except when it comes to updating images.

This site sells POD products and the product images displayed are coming from Because of the way the printify app works image (mockup) urls DO NOT get changed when a product is updated, so I’m assuming netlify’s Image CDN has no way of knowing to update.

I have narrowed the culprit down to image CDN because:

  1. The updated images are seen on my development server, once the browser cache has been updated.
  2. In dev tools, the url of an image on the development server is exactly the same as that on the published site.

I’m open to suggestions on how to work around this issue.
