Start with the file
Confirm that it opens locally, fits the stated size limit and uses a supported format. A file stored only in a cloud library may need downloading before a browser can send it reliably.
Test in a controlled order
- Wait for the current request's status or timeout.
- Check your connection with an ordinary page load.
- Try a small, non-sensitive permitted sample.
- Record any visible error before retrying.
If the sample works but the original does not, inspect the original's encoding and dimensions. If both fail, the problem may concern the browser or service rather than the photograph.
Keep privacy in the retry
Do not send the same private image to multiple unrelated providers as a diagnostic shortcut. Review the service's help and cleanup options. In Facehunch, upload success and a provider result are separate stages, and restricted test coverage remains unchanged by a retry.
Continue with image-search troubleshooting.
