executar script em php - captcha

[guhfloripa 0]

oi peguei um script na net, em php que consegue descobrir captcha simples, e mostrar o que esta escrito. Consegue ler uma figura e mostra isso numa string.

 

este é a pagina em cache do google do site que encontrei este scritpt:

http://74.125.93.104/search?q=cache:DA_hbt...-BR&ct=clnk

 

e este eh a pagina em q encontrei o script do captcha:

http://www.alixaxel.com/wordpress/2007/06/...aptcha-decoder/

 

Porem a pagina atual esta fora do ar, por isso que passei o captcha para vcs obrigado.

 

O script que eu gostaria de executar é este abaixo:
