I am using interop excel Library.
I am successful in creating excel so far but I want to embedd the object into excel cells which I am unable to do so.

using this code :

foreach (DataRow r in dt.Rows)
            {
                iRow++;
                // add each row's cell data...


                iCol = 0;
                foreach (DataColumn c in dt.Columns)
                {
                    iCol++;
if (c.ColumnName == "Vendor Filename" && r[c.ColumnName] != null)
                    {
                        OLEObjects oleObjects = (Microsoft.Office.Interop.Excel.OLEObjects)


                        xlWorkSheet.OLEObjects(Type.Missing);

                        oleObjects.Add(
                            Type.Missing,   // ClassType
                           HttpContext.Current.Server.MapPath("~/Entitelement_Files/" +"xyz.jpg"),           // Filename
                            true,           // Link
                            false,          // DisplayAsIcon
                            Type.Missing,   // IconFileName
                            Type.Missing,   // IconIndex
                            Type.Missing,   // IconLabel
                            Type.Missing,   // Left
                            Type.Missing,   // Top
                            Type.Missing,   // Width
                            Type.Missing    // Height
                        );
                        objSheet = (_Worksheet)xlSheets.get_Item(1);
                        excel.Cells[iRow+1, iCol] = oleObjects;
                    

                    }
                    else
                    {

                        excel.Cells[iRow + 1, iCol] = r[c.ColumnName];
                    }
                }
            }

But this is not letting me achieve the task.
The pic is inserted randomly and moreover I am not sure what can be my object as it could a simple text file or a image or DB file or so on.

Kindly help.
Thanks
