Referenced .png images not displaying when file is referenced into another .dwg, but display perfectly in original file.

I have a .dwg with attached .png images that displays perfectly when opened in DraftSight. This .dwg is referenced into another .dwg file as an xref (it was originally done in AutoCad 2010). When I open this "new" file in Draftsight the images say they are loaded but do not display. Reloading doesn't fix the problem.

Any ideas?  Thanks!
