How Do I "EMBED" Not "ATTACH" An Image/photo Into The BODY Of A Yahoo E-mail?

You have to attach them, but the recipient will still be able to see
the files embedded in the e-mail they receive. However, if what you
want to do is send them an e-mail, where you can add some text in
between pictures, say a title or description, that's not gonna work
from the Yahoo website, because Yahoo will display all pictures at
the bottom of your message. To be able to add text and pictures in
whatever position you want them to be, you need an e-mail application,
such as Outlook Express or Microsoft Outlook for Windows, Mail or
Microsoft Entourage for Apple.
