Insert Image into Excel doesn't seems to work anymore.

Hi @hy-net,
Unfortunately, that sample is out of date. in v3+ the .Close() method has been removed. That sample repo is archived, so it will be difficult to update But you can change .Close() to .Dispose() and that will resolve the issue, although the more modern and less error prone method is to use a using statement:
void CreatePackage(string sFile, string imageFileName)
{
    try
    {
        if (File.Exists(sFile))
        {
            File.Delete(sFile);
        }
        // Create a spreadsheet document by supplying the filepath.
        using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(sFile, SpreadsheetDocumentType.Workbook))
        {

            // Add a WorkbookPart to the document.
            WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
            workbookpart.Workbook = new Workbook();

            // Add a WorksheetPart to the WorkbookPart.
            WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
            worksheetPart.Worksheet = new Worksheet(new SheetData());

            // Add Sheets to the Workbook.
            Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());

            // Append a new worksheet and associate it with the workbook.
            Sheet sheet = new Sheet()
            {
                Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart),
                SheetId = 1,
                Name = "mySheet"
            };
            sheets.Append(sheet);

            var drawingsPart = worksheetPart.AddNewPart<DrawingsPart>();

            if (!worksheetPart.Worksheet.ChildElements.OfType<Drawing>().Any())
            {
                worksheetPart.Worksheet.Append(new Drawing { Id = worksheetPart.GetIdOfPart(drawingsPart) });
            }

            if (drawingsPart.WorksheetDrawing == null)
            {
