Pre-Publication Image Check for Editors: Evidence Review Workflow
A pre publication image check should happen before an editor publishes a high-stakes image claim. The workflow starts with the original file, then reviews provenance, metadata, byte markers, source context, and what still remains uncertain before the newsroom writes a caption, note, or takedown decision.

Key takeaways
- Always request the original file before reviewing screenshots or reposts.
- Treat trusted provenance as stronger evidence than visual intuition alone.
- Document uncertainty in the editor note instead of flattening the result into a binary label.
- Escalate high-impact cases when provenance fails, metadata is missing, or claims could harm a source.
1. Preserve the original file first
A publishing workflow loses important evidence if the team starts from a screenshot, social repost, or messaging-app forward. Save the original upload, preserve filenames when possible, and record where the file came from before anyone edits it.
If the only available copy is a repost, note that the review is weaker because provenance manifests, EXIF, and provider markers may already be gone.
2. Review provenance before detector-style clues
A pre publication image check should prioritize C2PA Content Credentials, signature status, trust policy, and asset binding before pixel-based detector clues. Provenance answers where the file says it came from when supported data exists.
If a manifest is missing, say the evidence is absent or inconclusive. Missing provenance is not proof that the image is fake.
3. Separate metadata, marker-only, and camera-like support
Metadata fields, XMP tags, provider strings, and camera-like EXIF patterns all sit below trusted provenance in the evidence stack. They can support or challenge a claim, but they should be labeled clearly so editors do not confuse marker-only hints with verified origin.
This is especially important when a photo looks plausible but the file carries AI-related strings or unexplained editing tags.
- Trusted provenance: strongest file-based signal when signature, trust, and asset binding validate.
- Marker-only evidence: useful lead, but not equivalent to signed provenance.
- Camera-like support: lowers immediate suspicion, but does not prove the depicted event is real.
4. Write an editor note that matches the evidence
The final step is communication. If the evidence is mixed, the note should say so directly: for example, that no supported provenance was found, metadata was stripped, or the original file could not be obtained.
Avoid publishing language that claims the tool proved the entire story true or false. A safer note explains what was checked, what was found, and what still could not be verified.

FAQ
What if the source only provides a screenshot?
Run the review, but note that screenshots often remove the strongest provenance and metadata signals. Ask for the original file before making a high-confidence claim.
Should editors trust a detector score on its own?
No. Detector scores can be useful leads, but editorial decisions should also review provenance, metadata, source context, and impact if the decision is wrong.
When should a newsroom escalate the case?
Escalate when the image supports a sensitive allegation, major breaking-news claim, legal risk, or potential harm to a person or organization if the conclusion is wrong.
What should a pre-publication checklist record?
Record the source, original-file status, provenance result, metadata result, any marker-only clues, reverse-search findings, and the exact wording used in the editor note.
