Delete images

I'm using Paligo to manage my ZD content and will publish from Paligo to Zendesk. I notice, in test publishes, that with existing ZD articles, when Paligo publishes to ZD, it ADDS a new set of images to the ones already there (because Paligo uses a UUID naming convention to ID images for their database.) What I'm left with, after the first publish into ZD, is a duplicate set of images, ones with the original names (stock_web_image.png) and another with a complex UUID named version (UUID-[bunches of numbers].png)

Is there any way to find and delete the original images without having to go manually through my 800+ article repository and use the clunky check and delete process for each article?
