Hello, thank you for reaching out to Microsoft Q&A.
May I please confirm whether you have already linked your computer and mobile device using the Phone Link app?
- Open Phone Link on your PC and the Link to Windows app on your mobile device.
- Make sure both devices are turned on, connected to the internet, and properly linked.
Also, please make sure the photos you are trying to share are stored locally on your phone and not only in cloud storage apps like OneDrive or Google Drive. Open the photos in your phone’s Gallery/Photos app, then tap Share and check if Link to Windows appears as a sharing option.
If you still do not see the option, try uninstalling the Link to Windows app on your mobile device, reinstall it, and then set it up again to re-link your phone to your PC.
