¿Dónde puedo encontrar imágenes gratis?

¿No tienes tiempo o presupuesto para contratar a un ilustrador? ¿O quieres personalizar tus imágenes de la forma más sencilla posible?

Aquí te dejo una lista de sitios en los que puedes encontrar imágenes gratis (o casi) para tu proyecto.

IMPORTANTE: no es lo mismo "imagen gratuita" que " imagen que se puede usar". Buscar en Google Imágenes es gratis, pero eso no significa que puedas usar cualquier imagen que encuentres ahí. Muchas imágenes están protegidas por Copyright, así que mejor no meternos en problemas y asegurarnos de que tenemos permiso para usar las imágenes que queramos incluir en nuestro proyecto.

Las condiciones de uso de estas páginas pueden haber cambiado desde la publicación de este post. Es tu rsponsabilidad como usuario comprobar los términos de uso actualizados por ti mismo.
