Inserting a JPEG Company Logo/Address at the top of electronically generated BW Invoices.

Looking for advice from anyone who has successfully inserted a JPEG "company logo" at the top left of electronically generated PDF BusinessWorks Invoices.  I've been living with a Black and White logo of a certain resolution but it looks poor.  My attempts to insert a higher Res. file never succeeded since I couldn't get it inserted correctly and after numerous attempts with my Graphic Artist providing me various JPEG resolution files, I frankly gave up.  Thanks in advance for any guidance.
