All you have to do is copy your brush file into the proper brush folder, and click the Refresh Brushes button in the Brushes palette window. It’s actually pretty simple to install new brushes in GIMP. You can even create your own brushes to really unleash your creative vision. Custom brushes let you completely change the way your drawing and editing tools work, providing new texture, style, and more. One of the most exciting features of GIMP is the ability to use custom brushes.
