Use the below code in the download picture page:

C#

string strFileName ="pic.jpg";
byte[] bytes = // get byes from the database table using your DB code/function
Response.Clear();
Response.AppendHeader("Content-Disposition", "filename=" + strFileName);
Response.AppendHeader("Content-Length", bytes.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(bytes);
Response.End();
