Thanks.

As an even better time saver, I could add the internet shdocvw.dll
class to a form and then use it's methods to navigate to the binary
resource. The control on the VB form will put the binary into the
cache defined by the pre-existing control by the installation of
windows.

Can I change the form.[internetControl].[properties] while it is
running to cache the images to another directory?
