cannot send photos to laptop from iphone 6

There are a number of ways to do that so you may want to reply with how you are trying to do it, whether the computer is Windows or Mac, and what is happening. Noting that the title of the post states that the direction you are trying to move the photos is from the phone to a computer, among the methods:

via USB cable: Import photos and videos from your iPhone, iPad, or iPod touch to your Mac or Windows PC - Apple Support

via Photo Stream: My Photo Stream FAQ - Apple Support

via 3rd party app such as: http://www.photosync-app.com/

via iCloud Photo Library: iCloud Photo Library FAQ - Apple Support (on a Windows computer you can go to iCloud.com and select the photo and click the download button)
