How annoying! But I've had the same and ended up doing what Marcin (in
another response) did: created my own beamer template that matched what
our corporate style people wanted...

This should be easier. The following is untested but putting a line
like this at the start of your org file may do the job:
#+latex_header:
\usebackgroundtemplate{\includegraphics[width=\paperwidth]{<your_fig>}}
Try this out and let us know how you get on. Happy to help if you get
stuck.
