Hello HoayMing1,

Thanks for using Apple Support Communities.

If you would like to sync photos from your Windows PC to your iPhone, and have those synced photos create an album, then you will need to follow the directions outlined below.

Sync photos

You can sync photos to your device from an app on your computer, or from a folder on your computer.

3. Connect your iOS device to your computer.
4. Click on the device icon in iTunes.
   
5. Click the Photos tab.
