An attachment is a file that you can include as part of your email message. You can attach all types of files to your message, including word processor or spreadsheet documents, audio files, image files (.bmp, .jpg, .gif, etc.), web pages saved as HTML files, and more. You can attach up to 50 files with a maximum total message size of 20MB.
Create a new message, address it, and write the text of the message, as described in Composing a New Email Message, Addressing Your Message, and Writing Your Message.
Click the Attach button.

The Choose File or Open File window appears (depending on your operating system).
Locate the file you want to attach, select it, and click the Open button.
You return to the new message tab, which displays the progress of automatic Norton AntiVirus™ scan of the selected file.
Tip: Norton AntiVirus™ doesn’t let you to attach infected files.
To attach more files, repeat steps 2 and 3.

Tips:
You can’t attach the same file more than once to the same email message. You also can’t attach multiple files in one operation, or a folder containing multiple files.
Although AT&T Mail often shows attached images and HTML files within the messages you receive, it doesn’t display the files you attach within a message while you’re composing it. Instead, it lists the files in the attachments area. Attached images and HTML may appear within the text of the message when your recipients read it if their email applications support inline graphics and HTML content.
If you decide before you send the message not to include an attached file, just click the Remove link to detach it.

Tip: The Working Safely With Email Attachments includes additional information about attachments on email you send and receive.
When you’ve completed your message, you can send it.
