How to organise a large set of image-search results

Use three review groups

Separate confirmed copies, possible derivatives and unrelated similarities. Within each group, combine results from the same publication so a large site does not dominate your attention merely through repetition.

Review efficiently

1. Open one representative page per source group.
2. Check the image and caption at a useful size.
3. Record unique context or attribution.
4. Discard unrelated results with a short reason.

Twenty thumbnails from one shop may represent a single product photograph used across category pages. Counting each as independent evidence exaggerates the finding.

Keep a stopping point

Once the original question is answered, avoid collecting more unrelated pages. If your goal is a reuse audit, preserve a manageable list of actionable sources. A tidy, explained subset is more useful than an unreviewed export that makes weak and strong matches look equally credible.

Continue with responsible source checking.
