Locate the file first
Open the photograph in your device's normal photo or file application. Confirm that the full image loads, then use the application's supported export or save controls to create an accessible copy.
Retry with a clear input
- Choose the picker location containing the saved copy.
- Check that the format is accepted.
- Avoid selecting an album link or placeholder.
- Preview the file after selection when the service allows it.
A screenshot saved to Photos and a downloaded image saved to Files may appear in different chooser views. Switching between those views can be enough; granting broad library access is not always necessary.
Keep the original intact
Do not delete the source while troubleshooting. If the picker still fails, try a current browser or the provider's documented workflow with a non-sensitive sample. The problem concerns file selection, not whether the search index contains a match for your photograph.
Continue with image-search troubleshooting.
