title: converting a base 64 string to an image and saving it
body: <p>Here is my code:</p>
  
  <pre><code>protected void SaveMyImage_Click(object sender, EventArgs e)
          {
              string imageUrl = Hidden1.Value;
              string saveLocation = Server.MapPath("~/PictureUploads/whatever2.png") ; 
  
  
              HttpWebRequest imageRequest = (HttpWebRequest)WebRequest.Create(imageUrl);
              WebResponse imageResponse = imageRequest.GetResponse();
  
              Stream responseStream = imageResponse.GetResponseStream();
  
              using (BinaryReader br = new BinaryReader(responseStream))
              {
                  imageBytes = br.ReadBytes(500000);
                  br.Close();
              }
              responseStream.Close();
              imageResponse.Close();
  
              FileStream fs = new FileStream(saveLocation, FileMode.Create);
              BinaryWriter bw = new BinaryWriter(fs);
              try
              {
                  bw.Write(imageBytes);
              }
              finally
              {
                  fs.Close();
                  bw.Close();
              }
          }
  }
  </code></pre>
  
  <p>The top imageUrl declartion is taking in a Base64 image string, and I want to convert it into an image.  I think my set of code only works for images like "www.mysite.com/test.jpg" not for a Base64 string.  Anybody have some suggestions?  Thanks!</p>
