I just wrote some sample code on how to create GIF images in C#:

using System;
using System.Drawing;
using System.Drawing.Imaging;


public class Tester {
  static void Main() {
    Bitmap bmp = new Bitmap(79,121);
    Graphics graph = Graphics.FromImage(bmp);
    Font font = new Font("Times", 6, FontStyle.Italic);

    for(int i=0; i<10000; i++) {
      graph.Clear(Color.White);
      graph.DrawString(i + " - Test", font, SystemBrushes.WindowText, 1, 1); 
      bmp.Save(i + "foo.gif", ImageFormat.Gif);
    }
  }
}

To compile that code you have to make an reference:

$ mcs -r:System.Drawing pic01.cs

To create 10.000 images takes about 12 seconds on my notebook. If you prefer PNG it takes a little bit longer ~ 26s.
