GIMP is a freeware (GNU) PhotoShop like photo editor.

Installer at: 
  http://www.gimp.org/~tml/gimp/win32/downloads.html
  (links to http://www2.arnes.si/~sopjsimo/gimp/)


1) Run setup "(1) gtk+-1.3.0-20020912-setup.exe" (runtime libs)

2) Run setup "(2) gimp-1.2.4-20020907-setup-2.exe" (program)

3) For "GIF" save (proprietary) copy "gif.exe" into
   "plugins" ("C:\Program Files\GIMP\lib\gimp\1.2\plug-ins").

4) Run setup "plugin-pack.exe" to install extra plugins.


You are done. Launch the GIMP, and think of it like PhotoShop. One strange thing: many operations are done by right clicking in the image. For example, the File->Save is there, not in the Tools floating window that opens on startup of GIMP. So, to save, or change an image size, right click on the image and use the menus there.

How to install: You have to download both gtk+-1.3.0-20020912-setup.zip and gimp-1.2.4-20020907-setup.zip to be able to install The Gimp. Install gtk+-1.3.0-20020912-setup.exe first, and in then gimp-1.2.4-20020907-setup.exe. If you need to save GIF files, you also have to download gimp-1.2.4-20020907-lzw-setup.zip and install it.

Distributing: The Gimp is released under GNU General Public License, and GTK+ libraries are released under GNU Library Public License. These licenses allow you to freely distribute the programs, including on magazine cover CDs (so please don't ask me for permission to distribute The Gimp, because you can; I'm not the author of The Gimp anyway). Be careful, to distribute both the binary and source code of The Gimp though, it's a requirement of the GPL.

The installers are compressed with 7z packer, and require around 28 MB of free space on temporary drive. They also require at least 16 MB of free memory (if you get message "Data Error" while extracting, this most likely means that you don't have enough free memory). This way the installer is 4 MB smaller.
Important: This doesn't mean that you need to install 7z. The ZIP file is standard, created with PKZIP 2.50. Inside the ZIP file, is a self-extracting 7z archive (it's packed in ZIP because some firewalls don't allow downloads of EXE files). If you can't extract the ZIP file, you probably didn't download the complete file.
