	End Interface

[SIIGBF]

!!!!Notes:
To get a thumbnail for a shell item, simply cast the IShellItem instance to IShellItemImageFactory and call GetImage() on it. Usage may look something like this:

IShellItem ppsi = null;
	IntPtr hbitmap = IntPtr.Zero;
	// GUID of IShellItem.
	Guid uuid = new Guid("43826d1e-e718-42ee-bc55-a1e261c37bfe");
	SHCreateItemFromParsingName(filename, IntPtr.Zero, uuid, out ppsi);
	((IShellItemImageFactory)ppsi).GetImage(new SIZE(256, 256), 0x0, out hbitmap);
