 From a quick look at the code, I think the problem is that maImage() calls layout() itself (and in "traditional" graphics, layouts cannot be nested). In other words, maImage() always uses the entire "page".

Some options:

(i) you could try to figure out how to call the maImage.func() directly 
(basically do the rearranging of the data that maImage() does yourself).
(ii) you could try to figure out how to call the image() function 
instead (again, requiring you to rearrange your data). (ii) you could email the bioconductor help list (marray is a BioC package). (iii) you could email the package authors/maintainers directly.
