SQL & PL/SQL

Hi

Using Oracle PL/SQL (11gR2 and APEX4.2),  Is there a way to email users an embedded chart in the email body rather than attachment ?

Currrently I am able to do the following,

• use <img src = ...>  tag to specify the reference to the image file in the email HTML body, BUT user cannot see the image if they don't have permission to the file folder.
  or
• send an email to users with the attached image file, BUT user perfers to view the image in the email body as well.

So I would like to know whether it is possible to show the image inline ( in the email body ) to the user by referencing the attached image file ??

Thanks for your advice.
