I'm looking for quality 16x16 pixel icons for use in general web applications, that cover common web app concepts like users, links, images, tools, etc. They can be free or paid for, but must be available for commercial use. I'm lookin for something along the lines of WordPress's icons:
- Must be pixel-based, 16x16 size. No vector conversions.
- I'm looking for specific sets, not icon search sites. Don't send me to iconfinder.
- I'm looking for results from the experts on this site who have experience with this stuff, not from Google. Don't even try it.
