Displaying image from binnary data

the way create httphandller class in your application and like bellow.

public class ImageHandle : IHttpHandler {
   
    public void ProcessRequest (HttpContext context) {
        string imageid = context.Request.QueryString["ImID"];
              SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlcn"].ConnectionString);

        connection.Open();

        SqlCommand command = new SqlCommand("Select ImageColumn From TblImages Where ImageId="+imageid, connection);
               SqlDataReader dr = command.ExecuteReader();

        if (dr.Read())
        {
            context.Response.BinaryWrite((Byte[])dr[0]);
            //context.Response.BinaryWrite((Byte[])dr[1]);
        }
      
        connection.Close();

        context.Response.End();
    }
 
    public bool IsReusable {
        get {
            return false;
        }
    }

}

and in aspx page provide Image controls imageurl property like
Image1.ImageUrl="~/ImageHandle.ashx?ImID="+someid;
