With the relationship to the second content type properly defined (and possibly also required) you should be able to display the image requested. 

One problem area I've seen is the base tables defined.  You can see the base table in the export text of a given view right on top. 

If your base tables do in fact differ, then there are further nuances to the relational display in views, but it can be done.

Post back if you have more details to this view creation to guide a useful example.  I'll post more step by step instructions.
