databind pictureBox control to SQL server Northwind

[amazingpeople]

I have a winform with one pictureBOx and one datanavigator control. I want to
bind them to Northwind Employees table(Photo column) with the following code.
I can see the images and can navigate through them also thru the
datanavigator. But the images are not clear(hazy). can anybody help me out?

---------------------------------------------------------------------
string connString = @"Data Source=local\SQLEXPRESS;Initial
Catalog=Northwind;Integrated Security=True";
string data = "Select * from Employees";
SqlConnection conn = new SqlConnection(connString);

SqlDataAdapter da = new SqlDataAdapter(data, conn);
DataSet ds = new DataSet();
da.Fill(ds, "Employees");
this.pictureBox1.DataBindings.Add("Image", ds, "Employees.
Photo");
------------------------------------------------------------

Can anybody give me the correct code?
Thanks
