A great tool for those in webdev is Chami’s favicon generator. If you’re not familiar with favicons, they’re the little images that are linked to a website in the browser and appear in the address bar in Firefox and the favorites menu in IE. Favicons are useful for branding, marketing and dodging that annoying server error that Firefox issues everytime it requests a favicon.ico from your server when it doesn’t exist.
With the tool, all you need is a gif or jpg file that’s relatively scalable and preferrably square in dimensions. The icons the tool spits out are basically ready for primetime, although those in design may wish to create their own image pixel by pixel (16 pixels X 16pixels for those who count).
