Track Craigslist Views

Is it somehow possible to track craigslist ad views with Piwik?

You can use the Image tracker: Tracking API - Analytics Platform - Matomo

Not sure I understand how to use this feature is this correct:

Where do I set it up at, do I go to the dashboard and add new website but instead of website put a link to the image?

None of this is explained in the link you provided.
