I want to move photos from iPhone to computer

You can hook the phone to the computer using a USB cord and transfer the photos. If the photos are in the Photos app on the phone, open Photos on the computer. You can also use Image Capture to transfer the photos.

You can also transfer the photos using iCloud. If you are using OS 10.10.3 or above, open Photos, then go to Photos/Preferences/iCloud and set up syncing. Then go to System Preferences/iCloud or Apple ID, sign in, and check Photos syncing.

You can also do a manual download at iCloud.com/Photos. Hold down the command key while selecting the photos. Then click Download. Another option is to select a Moment, then click the Share button, and then cancelling the Share. The photos should remain selected.
