Ta aí, utilizando o jCROP do jquery...
voce executa esse crop ai via ajax...

E pronto =)

No meu caso eu passo as informacoes via post..

Eu baixo uma foto de OUTRO servidor... pra cropar NESTe servidor, e reenviar
pro outro.

=)

Este código foi desenvolvido para o CMS que criei pra a empresa aqui.
Ele é único, servindo varioas clientes, por isso a necessidade de utilizar
FTP.
