DeNunCianDo - Gimp Thread

Muchos deben conocer este programa, pero si como yo no quieren sentirse robandole a alguien y quieren una alternativa para el Photoshop pues creo que GIMP es la mejor opción.

Primero les dejo la descripción del programa y el link para la descarga si alguien no lo tiene... sin embargo, la idea del post es que se comenten trucos, tutoriales, preguntas, imagenes hechas con GIMP, etc, etc...

Introduction to GIMP

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.
It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.
GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.
GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X.
