Other Ways to Add Photos to an Email

You can click and drag a photo to an email message from almost any location, including the desktop, a Finder window, or an open document in another application. You can also access the Photo Browser by selecting Window on the Mail menu bar and clicking Photo Browser in the drop-down menu. You can drag from either the thumbnail view or the enlarged view in the Photo Browser. When you drag a photo to your message, a line is added to the email header for Message Size and Image Size. Don’t overlook this step, particularly if you are attaching several images. With photos at Actual Size or Large, your email may become too large for your provider to handle. You can also attach a photo to an email message by clicking the Attach paperclip icon in the message window toolbar. From there, locate the target image on your Mac and click Choose File.

Keep Files Small

When you send files via email, remember that you may have message size limitations with your email provider, and the recipients may have message size limitations with their email providers. As tempting as it may be to send full-size images, it’s usually better to send smaller versions. You can toggle between sizes to pick the best size for your email, but the Small and Medium options are most likely the best choice for emails.
