Uri graphicURI = new Uri("pack://application:,,,Resource.resx", UriKind.Absolute);
StreamResourceInfo ri = Application.GetResourceStream(graphicURI);
ResXResourceReader rsxr = new ResXResourceReader(ri.Stream);
IDictionaryEnumerator id = rsxr.GetEnumerator();
FileInfo[] filesInDir = rsxr.DirectoryToSearch.GetFiles();

In WPF .Net 4, how do find the and iterate the collection of Images from a resource?  I need to be able to find a particular image from the collection of images.  I have the the build selection as a resouce and copy all selected for the images.  I have 4 images of interest in this location path and can see them in the proejct Resources selection under Images.

I need to be able to deploy the application and earlier I was a known directory path with them in it but I won't be able to do that way because of deployment issues.  Thanks for any help...
