title: 403 Forbidden Issue in Amazon S3
body: <p>I'm using Amazon S3 for hosting images of users. Although I set all of them to be available for public (it means I could access images by their URLs in Chrome/Firefox/IE), I get a 403 Forbidden exception in my code. It's a thumbnail handler (C#, ASP.NET)</p>
  
  <pre><code>string file = context.Request.QueryString[IMG_PARAM].Trim().ToLower().Replace("\\", "/");
  
        if (file.StartsWith("http") || file.StartsWith("https"))
        {
            using (System.Drawing.Image im = System.Drawing.Image.FromStream(WebRequest.Create(file).GetResponse().GetResponseStream()))
            using (System.Drawing.Image tn = this.CreateThumbnail(im))
            {
                tn.Save(context.Response.OutputStream, this._formatType);
            }
        }
  </code></pre>
  
  <p>The exception comes from this part:</p>
  
  <pre><code>WebRequest.Create(file).GetResponse().GetResponseStream()
  </code></pre>
  
  <p>It's really strange to me, If there's something wrong with ACL or permissions, why I can see images with browser? Any help would be appreciated. </p>
