(e.g., a specific textbook, a research database like ResearchGate , or an online archive).
To help me find or draft the information you need, could you please clarify:
: Images used in machine learning, biological studies, or engineering tests.
(e.g., history, medicine, computer science).
: Specific artifact or site photos from an excavation (e.g., "Fxo" might be a site code).
