I've just posted a pre-release of GIMP Portable 2.2.12 and need some folks to test it out... especially if you've had problems with Portable GIMP or Portable Gaim in the past. For the unfamiliar, GIMP is an image editor taht supports most popular image formats. This release has many of the features of the other new apps, plus some new stuff:
Live CD Support - GIMP Portable fully supports running from a CD. Just extract it to your local hard drive, run it at least once and configure it to your liking, and burn it to CD.
In-Place Upgrades - GIMP Portable supports the ability to do what I'm calling an "in-place upgrade". This means that you can extract it right over an existing installation of GIMP Portable without losing any of your existing preferences and it'll Just Work (tm).
Language Selection - You can now specify the language that GIMP Portable will use independent of the operating system you're currently running it in. After running it at least once (and generating your default settings), head to GIMP Portable\Data\settings and open up GIMP PortableSettings.ini. In there, set LANG equal to the language you wish to use... de for German, for instance. It's blank by default, which means it will use the operating system default).
Autofix xmltok/xmlparse - As many users of previous versions have found, there are issues with compatibility on some systems. It seems the most common one is the presence of xmltok.dll and/or xmlparse.dll in the system32 or system directory. These can be sitting there from a long-ago upgraded or uninstalled app like the old version of Yahoo Messenger. When starting up, GIMP will cause a "The LIBFONTCONFIG-1.DLL file cannot start. Check the file to determine the problem." on Windows 9x or "The application failed to initialize properly (0xc0000142). Click on OK to terminate the application." on Windows 2000/XP. To work around this, the launcher will automatically detect the presence of these files and ask you if you'd like to disable them while GIMP Portable is running. It will restore them when you exit GIMP. There's an undocumented INI switch (AutofixIncompatibleFiles=true) that will let the launcher do it automatically without asking you. (I forgot to include this in the example INI and readme but will for the release)
