PGP Secure PDF don't show image on the body !

Hello to all 

I need a solution for this case: 

I use in my environment PDF Secure Message Delivery for encrypted mail to external users. 

When sending an image in the body of the email, PGP's secure on Mount puts images as PDF attachment and removes them from the provision originates in place so that the picture is only a reference (LINK) 

I need to show messages in the body of the email and not as an attachment.
