Using a jpeg as background image report

I want to use the lay-out of an invoice a background for my report. That way I have the logo, footer etc. in the right place.

When I add the .jpeg I only see a part of the image. It looks like the upper left corner of the image is not displayed at the upper‌‌ left corner of te report, but start halfway down and left of the page.
How can I display a jpeg of a A4 size pager properly as the background image?
