示例1: GetNodeImage

* This should retrieve a suitable icon for the file to display and return
* an Image pointer to it.
*
* \param pcNode The item from the remote view that needs an icon.
* \param bSmall If true, the icon should be 24x24. Otherwise it should be 48x48.
*
* \todo Ask the registrar for a suitable icon, based on the file extension.
* \todo Add basic file/dir icons as resources, and fall back to them if the icon file is missing.
