There are generally THREE ways:
1. Add as attachment, or
2. Drag into the e-mail
3. send as e-mail directly from a picture program such as Picasa or Faststone
Your title also says "how to install email program"; you may wish to look at Microsoft Mail and compare to Thunderbird. Microsoft Mail works fine for me.http://windows.microsoft.com/en-US/windows-live/essentials-other-programs
You can choose which programs in this package you want. I only chose the mail program.
*When you install the mail program, you will need to add your account which will require your username and password from your internet provider.
