Here's an updated version of dtb's answer for the v3 API using anonymous uploading (you need to register your app at http://api.imgur.com/ to get your client ID):

using (var w = new WebClient())
{
    string clientID = "<<INSERT YOUR ID HERE>>";
    w.Headers.Add("Authorization", "Client-ID " + clientID);
    var values = new NameValueCollection
    {
        { "image", Convert.ToBase64String(File.ReadAllBytes(@"hello.png")) }
    };

    byte[] response = w.UploadValues("https://api.imgur.com/3/upload.xml", values);

    Console.WriteLine(XDocument.Load(new MemoryStream(response)));
}

And the response is now like this (see http://api.imgur.com/models/image):

<data success="1" status="200">
    <id>SbBGk</id>
    <title/>
    <description/>
    <datetime>1341533193</datetime>
    <type>image/jpeg</type>
    <animated>false</animated>
    <width>2559</width>
    <height>1439</height>
    <size>521916</size>
    <views>1</views>
    <bandwidth>521916</bandwidth>
    <deletehash>eYZd3NNJHsbreD1</deletehash>
    <section/>

</data>

I Guess that the dtb solution is deprecated

    using (var w = new WebClient())
    {
        var values = new NameValueCollection
    {
        {"image", Convert.ToBase64String(imageData)},
        {"type", "base64"}
    };

        w.Headers.Add("Authorization", "Client-ID xxxxxxxxx");
       var response = w.UploadValues("https://api.imgur.com/3/image", values);
    }

another way to do:

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.imgur.com/3/image");
        request.Headers.Add("Authorization", "Client-ID xxxxxxx");
        request.Method = "POST";

        ASCIIEncoding enc = new ASCIIEncoding();
        string postData = Convert.ToBase64String(imageData);
        byte[] bytes = enc.GetBytes(postData);

        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = bytes.Length;

        Stream writer = request.GetRequestStream();
        writer.Write(bytes, 0, bytes.Length);

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Answer 3

I've just uploaded this image

using this code:

using (var w = new WebClient())
{
    var values = new NameValueCollection
    {
        { "key", "433a1bf4743dd8d7845629b95b5ca1b4" },
        { "image", Convert.ToBase64String(File.ReadAllBytes(@"hello.png")) }
    };

    byte[] response = w.UploadValues("http://imgur.com/api/upload.xml", values);

    Console.WriteLine(XDocument.Load(new MemoryStream(response)));
}

You might want to change your API key now :-)

The output was:

  <image_hash>IWg2O</image_hash>
  <delete_hash>fQAXiR2Fdq</delete_hash>
