Q: My Photo Stream is no longer adding photos to my PC.  How do I get my photos from my iPhone 5 to my PC's Photo Stream?

Hi jmy13,

Thanks for visiting Apple Support Communities.

Try these steps first if the Photo Stream on your PC is not updating:

• you can't connect to the Internet, iCloud Photos will not be able to send or receive updates to My Photo Stream. If necessary, troubleshoot your Internet connection on your PC, Mac, or iOS devices.
  
  
• Open the iCloud Control Panel and make sure that you're signed in to the same iCloud account that you're using on your other supported devices.
  • In Windows 8.1, go to the Start screen, click the down arrow in the lower-left corner, then click the iCloud app.
  • In Windows 8, go to the Start screen, and click the iCloud tile.
  • In Windows 7, choose Start menu > All Programs > iCloud > iCloud.
    
    
• Make sure that iCloud Photos or Photo Stream is turned on in the iCloud Control Panel. Click the Options button and make sure that My Photo Stream is turned on.
  
  
• Close and reopen the iCloud Control Panel.
  
  
• Restart your computer. This may sound simple, but it does reinitialize your network and application settings and can frequently resolve issues.
