Icons can sometimes be the difference between a nice looking theme and a plain looking one, as we continue to try to create new designs for WordPress blogs, and other blogging software, we increasingly need new icons to give it that extra edge.
DHTML Site has compiled a list of free icon resources, and while not all encompassing, it does highlight some of the best sources for icons that you can use for your theming needs.
The most popular, of course is the Silk Icon set, but I think people are slowly trying not to use it in part because of its high popularity. Or in other words, people are sick of seeing a million sites with the same icon set. I thought the Sweetie set looked really nice.
If you have any other great collections of free to use icons, please let me know. I’d love to find more icon resources.
