You can add visual effects to your digital pictures, write captions, pan, tilt, zoom, crop, eliminate red eyes, change the contrast, colour and enhance them. Other features include the ability to create slide shows, upload your photographs to your blog or website, burn them to CD or DVD, make a desktop image, create a screensaver, etc. The software is available for Windows and Linux.

Pixen is an innovative graphics editor for the Mac. It's designed from top to bottom for pixel artists—people who make low-resolution raster art like the sprites you see in old video games. But it's great for artists of all arenas: Pixen is like a very powerful MSPaint or a simpler, more agile Photoshop. And best of all, it's Free!

GIMP, often touted as a Adobe Photoshop replacement by its fans, allows you to create and edit images and photos. It has the usual facilities found in many commercial paint programs such as a variety of paint tools (Brush, Airbrush, Pencil, Clone, custom brushes and patterns, etc), full alpha channel support, layers and channels, transformation tools (rotate, scale, sheer, flip), multiple undo and redo, selection tools (rectangle, ellipse, free, fuzzy, intelligent, bezier, polygonal), animation support (including MNG), numerous file formats (BMP, GIF, JPEG, MNG, PCX, PDF, PS, PSD, PNG, SVG, TIF, TGA, XPM, etc) including conversion between different file formats, and so on. Supported systems include Windows, Mac OS X, Linux, FreeBSD and Sun Solaris. This is an open source program.

An Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.

Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development.

Tux Paint is a free, award-winning drawing program for children ages 3 to 12 (for example, preschool and K-6). It combines an easy-to-use interface, fun sound effects, and an encouraging cartoon mascot who guides children as they use the program.

Panoramio is a geolocation-oriented photo sharing website. Currently, some of the photos uploaded to the site can be accessed as a layer in Google Earth and Google Maps, with new photos being added at the end of every month. The site's goal is to allow Google Earth users to learn more about a given area by viewing the photos that other users have taken at that place.
