This is a plugin for GIMP version 2.0 and above. It allows you to convert images into RGB normal maps for use in per-pixel lighting applications. The goal is to completely clone NVIDIA's photoshop plugin, with a few new useful features. Downloads can be found on the project home page.

This simple plugin allows you to change the values of each color channel of each pixel of a layer by using mathematical expressions.
It is able to handle RGB* and Gray* images. Available operators are: +, -, *, /, , and %.
There are many functions available, such as sin, cos, sqrt, abs, min, max.
A few constants are provided (pi, e, j), and a lot of pre-defined variables are usable (w for image's width, h for image's height, x and y for cartesian coordinates in the image, etc.).
It creates a effect like a blackboard painting. It is very simple, it works with three layers, the top is in hue mode, the middle is in saturation and the bottom layer has a Sobel filter and is equalized. It can work on copy. Is based on Simon Budig sample script. It has a BSD license.
Crea un efecto parecido al de pintar en una pizarra. Es simple, trabaja con tres capas, la superior está en modo tono, la del medio en modo saturación y a la inferior se la aplica un filtro Sobel y luego se ecualiza. Permite trabajar en copia y tiene una licencia BSD.
This is a collection of Script-Fus that create Paths in the form of geometric shapes. Squares, rectangles, rounded rectangles, circles, ellipses, ovals, polygons, stars, flowers, gears, triangle waves, square waves, and sine waves are currently supported.
Version 0.91 is updated for GIMP 2.4.x! It now supports automatic stroking and filling!
RAWTex is a save plugin for GIMP 2.2.x, 2.3.x & 2.4.x allowing to create raw textures for the PC, PSP, NDS, PS2 or any other architecture handling chunky or compressed dxtc formats.
It can save raw RGBA (5650, 5551, 4444 or 8888) & indexed (T4, T8) textures (with 5650, 5551, 4444 or 8888 palette modes support) as well as DXTC (DXT1, DXT3, DXT5) compresssed ones, it supports the PSP textures swizzle mode and can generate mipmaps, it also have a color key feature to handle transparency and can convert grayscale pictures into alpha channel only textures.
Save for Web allows to find compromise between minimal file size and acceptable quality of image quickly. While adjusting various settings, you may explore how image quality and file size change. Options to reduce file size of an image include setting compression quality, number or colors, resizing, cropping, Exif information removal, etc.
