iPhone 5 Ios 9.2 my photos off WiFi tend to be blurred how can i stop this from keeping downloading when i reconnect to WiFi?

Hello Mikecici,

Thanks for using Apple Support Communities.

I understand that your photos are appearing blurry whenever your iPhone isn't connected to Wi-Fi. This indicates you likely have iCloud Photo Library enabled, with the Optimize Storage option. If you have cellular data disabled for Photos, then that would prevent your full-size photos from being downloaded without a Wi-Fi connection. To learn more about iCloud Photo Library, please take a look at the information in the link below.

Can I use iCloud Photo Library to save space on my device?

iCloud Photo Library automatically keeps all your photos and videos in the original, high-resolution version. Follow these steps to choose how you store your photos and videos on your device:

• On your iPhone, iPad, or iPod touch, tap Settings > iCloud > Photos or Settings > Photos & Camera, then select a storage setting.
• On your Mac, click Photos > Preferences > iCloud, then select a storage setting.

If you turn on Optimize [device] Storage, iCloud Photo Library will automatically manage the size of your library on your device, so you can make the most of your device's storage and access more photos than ever. All of your original, full-resolution photos and videos are stored in iCloud while device-size versions are kept on your device. You can download the original photos and videos over Wi-Fi or cellular when you need them.

If you turn on Download Originals, iCloud Photo Library will keep your original, full-resolution photos and videos in iCloud and on your device. Download Originals is the default setting for iOS devices with the free 5 GB storage plan and for all Mac devices.

You need an Internet connection to access an original photo or video that’s stored only in iCloud.
