copied!<p>Best bet is to create an HttpHandler that would return the image. Then bind the ImageUrl property on the asp:Image to the url of the HttpHandler.</p> <p>Here is some code.</p> <p>First create the HttpHandler:</p> <pre><code><%@ WebHandler Language="C#" Class="ImageHandler" %> using System.Drawing; using System.Drawing.Imaging; using System.IO; using System.Web; public class ImageHandler : IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.Clear(); if (!String.IsNullOrEmpty(context.Request.QueryString["id"])) { int id = Int32.Parse(context.Request.QueryString["id"]); // Now you have the id, do what you want with it, to get the right image // More than likely, just pass it to the method, that builds the image Image image = GetImage(id); // Of course set this to whatever your format is of the image context.Response.ContentType = "image/jpeg"; // Save the image to the OutputStream image.Save(context.Response.OutputStream, ImageFormat.Jpeg); } else { context.Response.ContentType = "text/html"; context.Response.Write("<p>Need a valid id</p>"); } } public bool IsReusable { get { return false; } } private Image GetImage(int id) { // Not sure how you are building your MemoryStream // Once you have it, you just use the Image class to // create the image from the stream. MemoryStream stream = new MemoryStream(); return Image.FromStream(stream); } } </code></pre> <p>Next, just call it inside your aspx page where you are using the asp:Image.</p> <pre><code><%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Image ID="myImage" ImageUrl="~/ImageHandler.ashx?id=1" runat="server" /> </div> </form> </body> </html> </code></pre> <p>And that is it.</p>
