How to attach a file into the body of an email

click compose then you right your msg

With the Web-based Yahoo! Mail service, you can attach to your email message a saved Web page or another document in HyperText Markup Language format.
When you attach an HTML file in this way, Yahoo! Mail won't display the HTML content of the attached file in the email message body.
To view the attachment, you must click the attachment tab above the email message.Yahoo! Mail and HTML
Yahoo! Mail is a Web-based service and it's fully compatible with the coding languages used to design and display Web content, including HTML and XML, Extensible Markup Language.
This means emails sent or received in Rich text or HTML format include clickable hyperlinks, graphics and other Web design elements.
However, Yahoo! handles emails with HTML attachments in a different way to email messages formatted with HTML.

About Yahoo! Mail Attachments
Like most email programs and online services, Yahoo! Mail offers an attachment feature for adding images, video clips, audio files and HTML document to email messages.
Some email programs display the content of the attached file in the email message body, but Yahoo! Mail doesn't provide this feature for any file attachment, whether it's an image, video clip or HTML document.


Viewing Yahoo! Mail Attachments When you attach an HTML document or another file to your Yahoo! Mail message, an "Attachments" button labeled with a "Paperclip" icon appears below the email address fields and above the email message body.
Clicking the "Attachments" button opens a pane containing a list of all files attached to the email. The email sender or recipient can open each attachment to view the files by clicking the file name.

Considerations

When sending a Yahoo! Mail with an attachment, always explain the content of the attachment in the main body of the email message.
A brief explanation will encourage the recipient to click and open the attachment to view the HTML document.
Bear in mind that many email services automatically block HTML attachments because of the security risk of opening HTML files, which can contain viruses, phishing scams or open Web pages with inappropriate content.
If you want to share a favorite Web page with a friend or contact, include a hyperlink to the Web page rather than a saved copy as an HTML attachment.

This seems to be a very common problem, you can try three things -

1, Switch to Classic Mail view
2, Compose a new message and attach the file first before typing anything in the subject line or the body of the email.
3, Upgrade to Internet Explorer 8

Reset browser... Tools >> Internet Options >> Advanced >> Reset

can't attach files in new at&t online mail, but it works fine in classic mode?

It is not possible to attach such large files through mail. Though you can use free public server to upload the files and then give the link to the person whom you want to download the files. You can use servers like rapidshare.com, ziddu.com, and many others.
Hope this helps.

Create a directory called Scans on your C drive

Scan each of your images and save them as a.jpg or whatever to the Scans directory.

Send an normal

You can add picture in the same way , just make sure that you place the cursor where you want each picture to show on the body of the email

You scan save the picture as a JPEG or the text document,PDF is prefered, to a temporary place, say desktop . then "attach" it to your eamil. You click ATTACH and then browse to the place the file is, and "Attach it" then ya send it.
You can also cut/copy paste INTO the body of ya email. That works too.
