Finally, if you want to create an ASCII gallery with thumbnails, it's pretty obvious that a thumbnail-size ASCII counterpart would hardly get close to an incoherent group of Xs and Ms. So what I have done so far is to get a screen capture of a maximized Notepad window showing the corresponding ASCII image, and importing it into a graphics editor (I use XNView, which is pretty good, or Paint Shop Pro) to shrink it to the desired size. It's also possible to open the text file in a word processor, using font size of, let's say, 4 points.

Darker

Normal

Bright

That's pretty much the "technique". Now, visit the ASCII HTML Fractal galleries to view some good examples of fractal pictures converted to ASCII art [go].
