With my ill gotten geek gold gains I wouls like to design some microbadges to announce I have arrived and to irritate and amuse others. Can anyone give me some tips on how to design a microbadge? I'm keen to do it with free software rather than buy one of those photoshop programs.
There's a favicon generator at http://www.chami.com/html-kit/services/favicon/ which can sort of be used as an image size reducing tool. It outputs, based on .jpg or other image format inputs, an icon file for use in web browsers. This won't work for a microbadge without some conversion, but in addition to the icon file, the generator provides a 16x16 pixel .png preview of the icon. You can submit .png's as microbadges. Its far from an elegant solution and pretty limited without further tools to refine the image. But, it does have decent image reduction, and that may be what you need.
