Create ASCII art

I've been looking for a tool to convert images to ASCII art,I did try some stuff but most had limitations or I had to pay then I found Photo2text.This is really cool,you can convert images to text files with no trouble and it is free.Its really helpful on orkut where I cant use images but ASCII art works great.But there are some small problems,like sometimes dark images and images with lots of shades does not appear correctly,I once tried an image of a huge fire but it didn't go right.It can be adjusted a bit by changing the brightness and controlling the character set.Anyway it works great for outlines of stuff.Now I can put a skull face in my orkut profile.Next time I want to check what my face looks like on ASCII art.
