# Get a field agent photo

Operation ID: `fieldagent.getAgentPhoto`

Retrieve a field agent's photo as a FHIR Binary resource. If ?binary_id= is omitted, it is auto-resolved from the agent's stored photo_binary_id extension, then from a Binary search by security context — either resolution fails with 400 if the agent has never uploaded a photo via fieldagent.uploadAgentPhoto. Only the agent themselves may read their own photo.
