Barrapunto

perdonar mi incultura... pero sería equivalente al código gpl que si lo usas y lo modificas tienes q liberarlo? o puedes incorporarlo en un proyecto comercial no-gpl sin problemas?

Segun el FAQ de su pagina:
"We select the Public Domain for the clipart in order to provide maximum flexibility and ease of use to the user. You can put the clipart into your own drawings without any affect on the copyright or license of your work. There are no requirements to include attribution of the clipartist. You can edit and modify the clipart as you wish and redistribute it under your own terms."
Asi que sin problemas :)
