What you're trying to do doesn't make sense: the browser trying to display your image will need to know where to download it from.

You should setup a special aspx page, dedicated to image generation, for example GetImage.aspx.

Your main page will then have img html tags pointing to this image generation page:

Then, inside GetImage.aspx, you retrieve the image from DB according to its id (fetched from URL parameter). The code would be something like:

command = connection.CreateCommand();
        command.CommandText = "Select FO_Roomdet_Image from fo_roomtype where FO_Roomdet_Id=1"; // or dynamically fetch id with Request.QueryString and properly escape it
        connection.Open();
        Reader = command.ExecuteReader();
        while (Reader.Read())
        {

            Response.ContentType = "image/jpeg"; // if your image is a jpeg of course
            Response.BinaryWrite((byte[])Reader.GetValue(0));                                 
        }
        connection.Close();
