I will be using Gimp and NVU to create my designs. Both of these programs are open source and freely available to download.
GIMP is a multi-platform photo manipulation tool. GIMP is an acronym for GNU Image Manipulation Program. The GIMP is suitable for a variety of image manipulation tasks, including photo retouching, image composition, and image construction.
GIMP has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.
GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.
One of The GIMP's strengths is its free availability from many sources for many operating systems. Most GNU/Linux distributions include The GIMP as a standard application. The GIMP is also available for other operating systems such as Microsoft Windows™ or Apple's Mac OS X™ (Darwin). The GIMP is a Free Software application covered by the General Public License [GPL]. The GPL provides users with the freedom to access and alter the source code that makes up computer programs.
Nvu (pronounced "N-view," for a "new view") is a free, open source software program that allows you to build websites and web pages using a simple WYSIWYG editor (what-you-see-is-what-you-get). Nvu makes creating web pages as easy as using a word processor and rivals such programs as Adobe's Dreamweaver and Microsoft's Expression Web, only for free! With Nvu's built-in site manager, connecting to your website and making changes is a snap.
