icons for your new website or web application, at the best price there is (free!)
Finding free quality icons for your site can be not only tedious but many times frustrating. I spent quite a lot of time searching for “mail” and “print” icons for the articles, and after some time I ended up making them myself, with functional but modest results. Fortunately, I came across Mark James´site some days ago and it really made my day! Mark currently offers three different sets of icons in .gif and .png formats, all of them are free to use and you can modify them to your liking (there´s one more about to be released). Mark only asks for a link back in case you decide to use them, which seems more than fair to me since his icons are professional, varied and really cute. In the end I am using the “print” and “mail” ones, plus the little green flags and the “user” icon on the “readers online” counter. Thanks Mark! 🙂
ps. Alternatively, you may like to try this icon collection.
if you need even more icons, may I recommend http://www.orangeicons.com – not exactly free but really really cheap(you can buy icons one by one there not sets)
