Image as background in base report

Version 4.3.1.2, English, Base of LibreOffice in Windows 7 english.
I would like to use an image (jpg or png) as a background within a LibreOffice Base report as can be done in a LibreOffice Writer document. Is this possible or can it be added to the functionality of Base?

In the menu Insert ==> Image.

This is different from a Base form, where similar setting is available at Format ==> Page ==> Background. The Page dialog for form does not have all of the same options as in report.
