Converting Crystal express checks to BI Publisher - how can I handle different logos by bu?

We are working on converting all of our crystal express checks to BI Publisher which we have setup by business units so that each display a unique company logo on the check.  We are looking to see if we can have one BI publisher check layout but have logic within the layout to handle all of the different logos by business units.  The logos which are all .jpg are to be stored on the server where the process scheduler is setup and running.    Is it possible to do this?  If so can someone help get me started on this I
