I like them. How do you download them, though?

Nice, thanks for pointing out good icons to use!

The linked download actually includes an icon library, which has all the images in all the icon sizes! Very convenient!
As a bonus, these images scale well at different sizes; are unobtrusive in design, so they can fit in with many different icon styles; have distinctive but subtle colour palettes; and aren't limited by having their replacement target already decided for them. That means that I can use these icons to replace Skype, or I can use them to replace a character folder, or I can use them as a button for a custom-programmed command that could do anything I want, or to launch any other program I want.

I think the person who designed this has a really good grasp on what makes a good icon image.
