How To Load Image From A Table. I Have Used Image Control.

You don't provide enough info relating to your question, such as where is the image stored, how is it stored (bytes, base64string, ect...), and what control you are trying to attach the image to.

However base on what you have provided this may help you.
exmple:

protected void Page_Load(object sender, EventArgs e) {
    if (Convert.ToInt16(Session["CompanyID"].ToString()) > 0) {
        con.Open();
        SqlCommand cmd = new SqlCommand(
                "select * from Companies where CompanyID="+
                Session["CompanyID"],con);

        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds,"Companies");
 
        if (ds.Tables[0].Rows.Count > 0) {
            Label1.Text = ds.Tables[0].Rows[0]["EmailID"].ToString();

            //Assuming you are storing the image as bytes:
            //===========================================
            //Get bytes from database field
            //Where "MyImage" is the Field name in your table
            byte[] img = ds.Tables[0].Rows[0]["MyImage"];
            Image image1 = ConvertImage(img);

            if(image1 != null) //check for image
                //Add to your image to the control, if exist
        }
    }
}

private static Image ConvertImage(byte[] img) {
    try {
        if (img == null || img.Length == 0)
            throw new Exception("Byte[] empty");

        //create stream & convert byte array to image
        MemoryStream ms = new MemoryStream(img); //add bytes to steam
        Image i = Image.FromStream(ms); //create image from stream

        ms.Dispose(); //clean-up, release stream resource

        return i; //image/null return value
    }
    catch(exception e) { //Error:
        //Do somthing
        return null; //genaric return value
    }
}
