Include the following scripts in your HTML

        accessKey,            // AWS Access Key
        secretKey,            // AWS secret Key
        expiresInSeconds,     // Expiration time in seconds from now
        httpMethod,           // HTTP method. GET, POST, etc
        s3Bucket,             // Your S3 bucket name
        path                  // Path to your S3 key. Do not include the bucket name in this.
        );
