The demo code you posted is using ITEMIDLIST values to keep track of local
files only, and then passing those ITEMIDLISTs to SHGetFileInfo() to get the
appropriate shell image list index when needed.  To do what you are asking,
you would first need to update the code to detect virtual items so that you
can specify filenames instead of ITEMIDLISTs.  When calling SHGetFileInfo()
for a filename, specify the SHGFI_USEFILEATTRIBUTES flag so that a physical
file is not needed, and remove the SHGFI_PIDL flag.  That way,
SHGetFileInfo() returns the index for the icon belonging to the specified
file extension.  For example:

    int __fastcall GetShellImage(const AnsiString &FileName, bool Large,
bool Open)
    {
        SHFILEINFO FileInfo = {0};
        int Flags = SHGFI_SYSICONINDEX | SHGFI_ICON | SHGFI_USEATTRIBUTES;
        if( Open )
            Flags |= SHGFI_OPENICON;
        if( Large )
            Flags |= SHGFI_LARGEICON;
        else
            Flags |= SHGFI_SMALLICON;
        ::SHGetFileInfo(FileName.c_str(), FILE_ATTRIBUTE_NORMAL, &FileInfo,
sizeof(FileInfo), Flags);
        return FileInfo.iIcon;
    }

Yes, you assign the iCon value to the TListItem::ImageIndex property.
