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 BT Yahoo! 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 not to include an attached file before you send the message, just click the Remove link to detach it.

After one or more files are attached, you can finish addressing, composing, and sending the message as you normally would.
