The file comes with an .AI illustrator file, .EPS file, and a .PSD file. It includes 28 different social icons and were all made in vector format so each icon can be scaled to any size! I also included a CS4 version for those who do not have CS5 or the new CS5.5 - I held a contest on Forrst.com, this is the post http://forrst.com/posts/What_Should_I_name_this_Icon_set-YJC... that who ever came up with a great name for this icon set would get an early release. So thanks to http://forrst.com/people/kbanman for the new name. - Enjoy :) Re-sale and or re-distribution is forbidden. If used elsewhere, credits back to http://icondeposit.com is appreciated.
