FREE Web Icons

I really like this one!  I was searching for pre made icons for a website that I'm working on.  With a limited budget I'm looking at free of charge royalty free images and found a great blog called instantShift.  They have the following article: 75 Free Useful Icon Sets for Web Designers and Developers.    Some of the links are dead now, but there are still a ton of great free icons you can use for your website.

I noticed that there are also a lot of content rich articles that web developers will find useful.   Check out instantShift.  I definitely recommend it!
