  You can add attachments at any time while you’re composing an email. Here’s how to do it: Click Attach Files—it’s below Subject:. In the window that opens, click Browse to find and select the file or photo you want. When you've got it, click it, then click Open. Click Attach Files again to inititate the upload of the file. Once the upload is completed, click the Continue to Message button. Repeat these steps to attach more files. Nice work. Look at you—adding attachments!
