The RootImageDirectory property has never been set correctly for me
using the provider supplied with the CE Code. I posted the issue
here a couple of times in past:

I always go in and set it myself and recompile the provider code, using this:
Private _RootImageDirectory As String = PortalSettings.HomeDirectory
Everything then seems to work OK.
