Show thumbnails from private vimeo videos

Question

I built a website with videos from vimeo. I want to show thumbnails from those videos on my site, but the normal API access won't help. The videos are private and can be accessed only in this site How can I get those thumbnails? Thanks

This is a class with options for Large, Medium and Small images.

 namespace VimeoWrapper
   {
    public enum ThumbnailSize { Large, Medium, Small };    
public enum VimeoErrors { NotFound, SizeNotExist, NetError }
    public static class VimeoHelper
    {
        public static string GetVideoThumbnail(string videoid, ThumbnailSize tns = ThumbnailSize.Large)
        {
            string query = String.Format("https://api.vimeo.com/me/videos/{0}", videoid);

            string accessToken = "Token from API";

            WebClient wc = new WebClient();

            wc.Headers.Add("Authorization", "bearer " + accessToken);

            string result;

            try
            {
                result = wc.DownloadString(query);
            }
            catch (System.Net.WebException e)
            {
                return VimeoErrors.NotFound.ToString();
            }

            try
            {
                dynamic jsonResult = JValue.Parse(result);
                switch (tns)
                {
                    case ThumbnailSize.Large:
                        return jsonResult.pictures.sizes[5].link;
                    case ThumbnailSize.Medium:
                        return jsonResult.pictures.sizes[3].link;
                    case ThumbnailSize.Small:
                        return jsonResult.pictures.sizes[1].link;
                }
            }
            catch (JsonReaderException e)
            {
                return VimeoErrors.SizeNotExist.ToString();
            }
            catch (Exception e)
            {
                return VimeoErrors.NetError.ToString();
            }

            return VimeoErrors.NetError.ToString();
        }
    }
}
