I needed some social bookmarking icons for my site, and was unable to locate any really simple icons to match my layout. So here's my own pack.
It's free to use for whatever you like and contains JPG in 4 sizes (170,85,32,16px) and also the vector EPS file if you want to change colors or make some other modifications.
Some of the icons currently included: RSS, StumbleUpon, Yahoo!, Google, Windows Live, Flickr, Vimeo, Technorati, Digg, Twitter, LinkedIn, MySpace, YouTube, Facebook, Delicious, Ma.gnlolia, Tumblr, Newsvine, Reddit, and some general UI icons.
The pack grows as I create new icons, so return in a while if you're interested in more!
There's no need to ask or credit me in any way, but it's nice to get links of it in use . Download below.
