Upload image to folder in project

Question

I have created empty SharePoint project in Visual Studio and have added SharePoint images mapped folder. Now I want to upload images to this folder which I get from Instagram. I have googled but have found code for uploading image to document library like below

 String fileToUpload = @"C:\YourFile.txt";
 String sharePointSite = "http://yoursite.com/sites/Research/";
 String documentLibraryName = "Shared Documents";

 using (SPSite oSite = new SPSite(sharePointSite))
{
using (SPWeb oWeb = oSite.OpenWeb())
{
    if (!System.IO.File.Exists(fileToUpload))
        throw new FileNotFoundException("File not found.", fileToUpload);                    

    SPFolder myLibrary = oWeb.Folders[documentLibraryName];

    // Prepare to upload
    Boolean replaceExistingFiles = true;
    String fileName = System.IO.Path.GetFileName(fileToUpload);
    FileStream fileStream = File.OpenRead(fileToUpload);

    // Upload document
    SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);

    // Commit 
    myLibrary.Update();
}
}

I wish to upload in my SharePoint mapped images folder. How to do it?

Update1

Ok now i want to upload in document library because its seems like we cannot upload to hive directly. so i have below code which downloads images from instagram. My question is then how can i use this image i get to upload in document library.

do
        {
            WebRequest webRequest = null;
            if (webRequest == null && string.IsNullOrEmpty(nextPageUrl))
                webRequest = HttpWebRequest.Create(String.Format("https://api.instagram.com/v1/tags/{0}/media/recent?access_token={1}", strtagName, strAccessToken));
            else
                webRequest = HttpWebRequest.Create(nextPageUrl);

            var responseStream = webRequest.GetResponse().GetResponseStream();
            Encoding encode = System.Text.Encoding.Default;


            using (StreamReader reader = new StreamReader(responseStream, encode))
            {
                JToken token = JObject.Parse(reader.ReadToEnd());
                var pagination = token.SelectToken("pagination");

                if (pagination != null && pagination.SelectToken("next_url") != null)
                {
                    nextPageUrl = pagination.SelectToken("next_url").ToString();
                }
                else
                {
                    nextPageUrl = null;
                }

                var images = token.SelectToken("data").ToArray();

                foreach (var image in images)
                {
                    imageUrl = image.SelectToken("images").SelectToken("standard_resolution").SelectToken("url").ToString();

                    if (String.IsNullOrEmpty(imageUrl))
                        Console.WriteLine("broken image URL");

                    var imageResponse = HttpWebRequest.Create(imageUrl).GetResponse().GetResponseStream();

                    var imageId = image.SelectToken("id");
                    object outputDir = null;

                    using (var imageWriter = new StreamWriter(String.Format("{0}\\{1}.jpg", outputDir, imageId)))
                    {
                        imageResponse.CopyTo(imageWriter.BaseStream);
                        imageResponse.Flush();
                        Console.WriteLine("copied {0}", imageId);

                    }

                    return imageUrl;

                }


            }

        }
        while (!String.IsNullOrEmpty(nextPageUrl));

This not the recommended way because

1. File System data are normally not backed up
2. If system upgrade/migration will loose files

3. Files will not get propagated to other servers on the farm - This will be a major problem in case of multi server farm

   SPSecurity.RunWithElevatedPrivileges(delegate()
   {
       string imagesPath = Path.Combine(SPUtility.GetGenericSetupPath("TEMPLATE"), @"LAYOUTS\Images");
   
       //Here you can use Normal File Operations to Path imagesPath
       using (System.IO.FileStream fs = System.IO.File.Create(imagesPath + FILENAME.EXTENSION))
       {
           //fs.WriteByte(i);          
       }
   });
