Share elsewhere and in other ways
Publish on social media or send pics directly
You can share photos on various social networks or other methods. To post on Facebook, Twitter, Flickr or Vimeo, first make sure you’ve signed in to your accounts for those services in the Internet Accounts pane in System Preferences. Next, return to Photos, select an album or some pictures, click the Share button and choose one of those networks.
The Share menu also includes a bunch of other common ways to share privately. At some point, you may want to send high-quality copies of photos to a family member or a friend for their library using email, probably because they don’t have an Apple device and find a direct email is less bothersome than downloading from a shared album at iCloud.com. Of course, Photos lets you share in this way, and you don’t even need to pay attention to the total size of images if you first enable the Mail Drop feature in Apple’s email client, assuming you use that. In Mail, go to Mail > Preferences > Accounts, select an account, click Advanced, and enable Mail Drop for that one. (If you want to use it with all of your accounts, you’ll have to repeat this for each of them one at a time.) Now if you send more than 20MB of photos, Mail will replace them with a download link, from which they’re available for 30 days. This ensures the recipient’s mail server doesn’t reject the message due to its total attachment size. See MF298 for more about Mail Drop.
Take care with Messages
You can send photos using the Messages app too, but consider whether the recipient has an Apple device. If your Mac and iPhone are configured to use the Continuity feature that relays MMS messages through your phone (see ‘Set up SMS and MMS with Continuity’ at apple. co/1RLIoj0), which is the method that’ll be used if the recipient isn’t using (or can’t use) iMessage, they may incur charges separate from their call plan’s data allowance.
You can publish directly to the big social networks, and to others if they provide a Share menu extension.
