With the number of pictures, songs, apps and videos that is commonly found on an iPhone, the small amount of storage space offered on the device can be filled up rather quickly. There are ways to manually manage that storage, such as deleting apps and media files, but that can be tedious. Fortunately there are a couple of options that you can use which do some space management for you.
One of those options is specifically focused on managing the way that your pictures are stored. Your iPhone SE in iOS 10 has an option that can intelligently sync files between your device and iCloud in an effort to maximize the storage space being used in both locations.
How to Optimize iPhone Storage by Pictures on an iPhone SE
The steps in this article were performed on an iPhone SE in iOS 10.3.2.

This can include uploading some of your pictures to iCloud and removing them from your device.
Step 1: Open the Settings app.
Step 2: Select the Photos & Camera option.
Step 3: Tap the button to the right of iCloud Photo Library to turn on that setting, then select the Optimize iPhone Storage option below.
Depending upon the amount of pictures you have on your device and the amount of free space you have in iCloud, you may be unable to fully manage your library in this manner.
Changing this setting is one of just many ways that you can optimize the storage on your iPhone. Our iPhone guide to storage optimization provides some additional ways that you can free up space for new apps, pictures, music and movies.
