I just read that a portable version of image manipulation program, GIMP, is now available for download.
If it works well enough that’s going to get a permanent home in my USB memory stick and unlike “Portable Photoshop”, this one is completely legal to copy and share.
GIMP Portable version 2.2.13 has been released. GIMP Portable is the full-featured GIMP image and photo editor bundled with a PortableApps.com launcher as a portable app, so you can edit your photos and images on the go. This new release updates the included GIMP to 2.2.13, adds Vista compatibility, correctly cleans up GTK’s bookmark and thumbnail files and features a greatly improved startup speed thanks to the new launcher’s plugin processing.
