Application is bombing when trying to access a file.

I am not sure how to setup the file name.

 string DirectoryName = Directory.GetCurrentDirectory();
            string AppPath = Application.StartupPath.ToString();
            Bitmap CWBLogo = (Bitmap)System.Drawing.Image.FromFile(AppPath + "\\..\\..\\Images\\CWB.bmp", false);

            Excel.Range rangeimg = excelWorkSheet.get_Range("B" + count.ToString(), "B" + count.ToString());
            Clipboard.SetDataObject(CWBLogo);
            rangeimg.Select();
            excelWorkSheet.Paste(rangeimg, false);

Can someone help me fix this.
