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.
The Unidentified Flying Raw (UFRaw) is a plug-in to read and manipulate raw images from digital cameras and to load them into the Gimp. UFRaw reads raw images using Dave Coffin's raw conversion utility - DCRaw. UFRaw supports color management workflow based on Little CMS, allowing the user to apply ICC color profiles.

The plug-in loads common uncompressed AVI files into multilayer images. It saves multilayer images to uncompressed AVI. Audio is discarded, only one video stream is supported. Compressed AVIs may be loaded using mencoder to import.
This Gimp plug-in is a simulation of a streak camera. A streak camera images an object through a slit - thus getting a kind of "one dimensional image". This image is propagated along the second dimension of the image plane at a constant speed. The result is a picture of the time dependency of the object. The plug-in takes a film (multilayer image), cuts a slice of selectable width and position out of each layer and puts the slices together to the streak image.
This Gimp plug-in splits an image into layers. The plug-in cuts an image into a number of rows and columns and composes a new multilayer image (film) of these pieces. It's just the reverse of the poster plug-in.
The Image Subtraction plugin compares each pixel of two given images and, if they are equal, put a transparent pixel on the new image. Otherwise, put on the new image the pixel from the primary image. It is useful if you want to isolate objects from two seemed images. The plugin has also a threshold slide bar.
This Gimp plug-in creates a new image/film by periodically extracting layers from another image. It takes one interval (number of sequent layers) every period. The number of periods can be limited.
