how to display images from folderto gridview in asp.net

Question

 My code as follows

protected void Page_Load(object sender, EventArgs e)
{
Lstfaculty.Items.Add("Raj");
Lstfaculty.Items.Add("suresh");

Lstfacid.Items.Add("1");
Lstfacid.Items.Add("2");

SetInitialRow();
}

private void SetInitialRow()
{

DataTable dt = new DataTable();
DataRow dr = null;
dt.Columns.Add("Faculty Name", typeof(string));
dt.Columns.Add("Faculty ID", typeof(string));
dt.Columns.Add("Photo",typeof(string));
for (int i = 0; i < Lstfaculty.Items.Count; i++)
{
dr = dt.NewRow();
dr["Faculty Name"] = Lstfaculty.Items[i].Text.ToString();
dt.Rows.InsertAt(dr, i);
}
for (int i = 0; i < dt.Rows.Count; i++)
{
dt.Rows[i]["Faculty ID"] = Lstfacid.Items[i].Text;
gvfaculty.DataSource = dt;
gvfaculty.DataBind();
}
}

When i execute my above code output as follows in Gridview

Faculty Name Faculty ID Photo

Raj 1
suresh 2


The above Raj and suresh images are stored in under E Folder Facultyimage.

in this Facultyimage folder(E Folder) the Raj and suresh images are there.

i want output as follows in Gridview

when i click the Raj(Faculty Name) in the gridview, i want to display the Raj image in the Photo column in gridiview.

Similarily when i click the suresh(Faculty Name) in the gridview, i want to display the suresh image in the Photo column in gridiview.


for that how can i do in asp.net using Csharp.
