Its easy to paste picture pedigrees into emails as shown below:
Just select the pedigree form and entry, adjust the picture size using your normal zoom controls (hold CTRL down and use the mouse wheel) then use Edit-Copy Image. In your email, just paste the image. The image can also be resized in the email.
