Inkscape 0.48 Essentials for Web Designers (Slashdot)
Inkscape is an open source 2D drawing tool that helps you create graphic designs, from simple buttons and logos to full blown posters and web page designs. Similar to Adobe Illustrator or CorelDraw, inkscape gives you a vector based graphics tool that uses the W3C Scalable Vector Graphics (SVG) format.
Inkscape is easy to use, although learning the tricks that make designing a web site look great are more involved. The Inkscape 0.48 Essentials for Web designers is specifically focused on helping you to create your first web site designs and does a great job of getting you started. Most if not all the techniques covered are relevant to creating other graphic works too, so its useful as a general Inkscape tutorial.
