My ImageHandler doesn't work

Question

I am trying to code a simple handler that should return an image URL so that I can display it on my website. This is how my handler looks like:

<%@ WebHandler Language="C#" Class="KameraHandler" %>

using System;
using System.Web;

public class KameraHandler : IHttpHandler {

    public void ProcessRequest (HttpContext context) {
        context.Response.Write("http://web.scott.k12.va.us/martha2/dmbtest.gif");
    }

    public bool IsReusable {
        get {
            return false;
        }
    }
}

and this is how I call my handler but It just doesn' work.

protected void AraLinkButton_Click(object sender, EventArgs e)
{
     KameraImage.Src = "~/GenericHandler/KameraHandler.ashx;
}

Answer 1

Your image handler is supposed to return the raw bytes of an image (and with the appropriate Content-Type), not the URL of an image.

You should set the src directly to that (external) URL.

Alternatively, you could make your ASHX send a redirect to that URL, or make it forward the contents of that URL.
