I'm not sure if you can do this in Express but:
1)Add a new resource file to your project.
2)Add a new resource to your resource file
-> On the Add Resource dialog click "Custom..."
-> For Type: enter whatever you wish "My_PNG" for example
3)Add your "resources" under that new folder in your resources.rc tree.
4)Access those resources using the ::FindResource() and ::LoadResource() functions of the WIN32.
Note: This approach imbeds the resources directly into the .EXE so it may *not* be exactly what you're looking for, but it is what you asked for...
