Claim photographs lose context when they are downloaded, renamed, and forwarded without a record. A custody log preserves the supplied file, its reported source, and each authorized transfer. It does not decide what the image proves.
Register the original receipt
Capture claim or load reference, sender, receiving account, receipt timestamp, original filename, file type, size, and secure storage link. Where approved tooling supports it, record a hash for duplicate detection. Never edit the original image.
The sender's description belongs in a separate reported-statement field. A filename or message can provide context, but it does not independently establish when, where, or why a photograph was taken.
Create derivatives deliberately
If the team needs a resized, redacted, or annotated copy, retain the original and record the tool, operator, time, purpose, and output link. Label the derivative clearly. Do not allow a compressed messaging copy to replace the source file.
Log every handoff
For each transfer, capture sender, recipient, approved channel, time, file set, and delivery evidence. Restrict access according to the carrier's claim and privacy rules. Public links and personal storage accounts do not belong in the chain.
Separate custody from interpretation
Administrative staff can organize files, identify missing references, and route a packet. They should not assess damage, determine causation, assign liability, estimate loss, or decide claim strategy.
Test the trail
Choose an original, a derivative, a duplicate candidate, and a transferred packet. A reviewer should locate each file and reconstruct its movement. Any unexplained change becomes an exception.
Working standard
The log is dependable when each image retains its origin, transformations, access history, and current location. Evidentiary and claim conclusions remain with qualified owners.
