Side by side
What a patrol finds
A patrol asks Google and TinEye where an image appears on the web, then compares every match with the original. Here one patrol covers both sets: protected images from the galleries, and the unprotected images, which are different pictures shown as ordinary files.
No side-by-side patrol yet
Start one from Manage → Patrols. It searches every unprotected image and the same number of protected ones.
Search engines only know about pages they've crawled, so a new site needs a few days to weeks before either set can turn up. The site's sitemap lists the unprotected files to help.
