Ummm...I hate to tell you this but you're not even close to creating an Excel file. You're setting a content type of Excel, but the content you're writing is HTML, NOT and Excel file.

With the code you have, you can't show an image. I suggest you Google for "OpenXML SDK" and use that for creating an Excel file. Warning! The learning curve for the SDK is kind of steep.

Here is a snippet to export image. Please use Microsoft Excel Liberary:

C#

protected void btnExportExcelWithImage_Click(object sender, EventArgs e)
{
    var xlApp = new Excel.Application();
    Excel.Workbook xlWorkBook = xlApp.Workbooks.Add();
    Excel.Worksheet xlWorkSheet = (Excel.Worksheet)xlWorkBook.Sheets[1];

    xlWorkSheet.Cells[1, 1] = "http://csharp.net-informations.com";
    xlWorkSheet.Cells[2, 1] = "Adding picture in Excel File";

    xlWorkSheet.Shapes.AddPicture(@"C:\Users\PGoel\Desktop\pp.jpg", MsoTriState.msoFalse, MsoTriState.msoCTrue, 50, 50, 300, 45);

    xlWorkBook.SaveAs(@"C:\Users\PGoel\Desktop\csharp.net-informations.xls", Excel.XlFileFormat.xlWorkbookNormal);
    xlWorkBook.Close(true);
    xlApp.Quit();

    Marshal.ReleaseComObject(xlApp);

    //MessageBox.Show("File created !");
}
