How to Email a Photo in Outlook
Emailing a photo will often reduce the size automatically. Using the Add File feature will send the photo in the same manner as a document and will not condense the file size.
Start your email
Select Add file
Go to Library, Pictures, or wherever your photos are stored and click on the one you want.
Email to firstname.lastname@example.org.
How to Email a Photo Using an Apple Device
Go to Photos on your Apple device and select your photo. Press the Share icon (square with Up arrow), then the Mail icon.
Enter email@example.com in the To field and type your email.
When you hit Send (Up arrow), your device will prompt you with size options. Select Actual Size and the email will be sent.
Additional methods may be available for other devices. For example, from webmail, you can start an email, click on the paperclip, select your file and your document will retain its original size.
