https://github.com/ranjit-singh-cc/DownloadImagesByUrl

Code wise it pretty much simple – You put all the image URLs in url.txt file, and tool iterate over all those URLs and download it in provided destination folder

static void Main() {
	Console.WriteLine("Enter destination folder path to save images: ");
	string destinationFolder = Console.ReadLine();
	string urlFileName = "urls.txt";
	if (Directory.Exists(destinationFolder) == false)
		Console.WriteLine("destination folder not found");
	else if (File.Exists(urlFileName) == false)
		Console.WriteLine("urls.txt file not found");
	else {
		string[] urls = File.ReadAllLines(urlFileName);
		int count = 0;
		Console.Write("Images download: 0");
		foreach (string url in urls) {
			if (DownloadImage(url, Path.Combine(destinationFolder, Path.GetFileName(url)))) {
				count++;
				Console.Write("\rImages download: {0}", count);
			}
		}

		Console.WriteLine("\n{0} images download", count);
	}

	Console.WriteLine("Press any key to exit");
	Console.ReadKey();
}

private static bool DownloadImage(string imgUrl, string fileName) {
	bool error = false;
	try {
		using (WebClient client = new WebClient()) {
			Stream stream = client.OpenRead(imgUrl);
			if (stream != null) {
				Bitmap bitmap = new Bitmap(stream);
				ImageFormat imageFormat = ImageFormat.Jpeg;
				if (bitmap.RawFormat.Equals(ImageFormat.Png)) {
					imageFormat = ImageFormat.Png;
				}
				else if (bitmap.RawFormat.Equals(ImageFormat.Bmp)) {
					imageFormat = ImageFormat.Bmp;
				}
				else if (bitmap.RawFormat.Equals(ImageFormat.Gif)) {
					imageFormat = ImageFormat.Gif;
				}
				else if (bitmap.RawFormat.Equals(ImageFormat.Tiff)) {
					imageFormat = ImageFormat.Tiff;
				}

				bitmap.Save(fileName, imageFormat);
				stream.Flush();
				stream.Close();
				client.Dispose();
			}
		}
	}
	catch (WebException ex) {
		error = true;
		Console.WriteLine(ex.Message);
	}
	catch (ExternalException ex) {
		error = true;
		Console.WriteLine("Something is wrong with Format -- Maybe required Format is not applicable here : {0} ", ex.Message);
	}
	catch (ArgumentNullException ex) {
		error = true;
		Console.WriteLine("Something Wrong with Stream : {0}", ex.Message);
	}

	return !error;
