Reading images can still be automated, it just takes a lot more time to
write a program to do so. A simple paragraph with text would be easy
(relatively speaking) for a program to decipher and automatically answer.
That's why you make the image "screwy"... the letters are tilted,
overlapping, wavy, colored, or complex backgrounds, etc. Even the best of
those images can be read by computer programs, though, although very few
people would be able to write that program.
