Retrieve image from DB and displaying along with components.

Question

Hi everyone,

Currently i have a aspx page called game.aspx, which contains various components and a button called 'show image' when i press this button i want the image to be retrieved from the sql database and show on game.aspx

At the moment I am using Response.BinaryWrite to display the image to a aspx page called image.aspx, code shown below:

namespace WebApplication.MemberPages
{
    public partial class Image : System.Web.UI.Page
    {
       protected void Page_Load(object sender, EventArgs e)
       {
          }

       public void GenerateImage()
        {
            Byte[] content = game.RetrieveImageBinary(); //Gets binary data from the database
            System.Web.HttpContext.Current.Response.BinaryWrite(content);
            System.Web.HttpContext.Current.Response.ContentType = "image/jpg";
        }
     }

In game.aspx i have a imagebox where the source is 'image.aspx'
Code: <asp:Image ID="Image2" runat="server" ImageUrl="Image.aspx" />

This displays the image correctly, although when doing so all other components that where on the game.aspx page have all disappeared!!

My question is am i doing anything wrong? Is Response.BinaryWrite the best solution to the problem? (i am willing to take different approaches).
Due to the program being a web application I don’t have access to a picturebox(would have made life a lot easier) and i am not to keen on making a temporary file.

Thanks

Since no one bothered to reply i decided to go on a personal mission to solve this problem, so if your looking for the answer you have come to the right place my friend. the answer is http handlers here is a copy and paste job of how i did mine: web.config file: (WebApplication.ImageHandler, WebApplication = class name, namespace) Image tag: (url is pointing to your http handler, im also passing a parameter to get a specific image) http handlers .ashx code: public class ImageHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { int _imageId; if (context.Request["id"] != null) //Parameter being passed from the image tag { _imageId = int.Parse(context.Request["id"]); } else { throw new ArgumentException("No parameter specified"); } Game game = new Game(); Byte[] image = game.RetrieveDB(_imageId); context.Response.BinaryWrite(image); } public bool IsReusable { get { return false; } } } I hope this helps and is usefull because i went absolutely crazy for 2 week trying to find this out.
