Answer 1

Store them as BLOB (Binary Large Object) and store the file stream, which basically is a byte array. Normally the file is stored on a server and the database only holds the file path and name. You will have to make space for a BLOB data type in your database in SQL server will allow images of 8000 bytes:
BLOBData varBinary(8000)

// Using DataTable as a mockup database.
System.Data.DataTable table = new System.Data.DataTable();
table.Columns.Add("file name");
table.Columns.Add("data");

// Read data from file.
byte[] stream = System.IO.File.ReadAllBytes("th.exe");
// Add the file to the db, don't know how you add data to your database.
table.Rows.Add("th.exe", stream);
// Create a filestream that will write data to disk (in a file).
System.IO.FileStream save = new System.IO.FileStream((string)table.Rows[0].ItemArray[0], System.IO.FileMode.Create);
// Retrieve the data from the database, don't know how you do this with your database.
byte[] data = (byte[])table.Rows[0].ItemArray[0];
// Write data to the file on disk.
save.Write(data, 0, data.Length);
