Replying to Address Bar Icon!?!

A lot of sites lately have icons in the address bars that some sites call favicons, but i noticed newschoolers does not.  This is a feature that does make sites look a bit more legit.  I'm sure many of you frequent SAC and whiskeymilitia, and have seen the icons there.  I think it is time that NS upgrade and I have took the liberty of helping make the first step.  Using an online site (which I am not affiliated with or endorsing) I have created some NS favicons.  I'm very new to this, but thought if it was already done it would be easy enough for the site manager to try out.  I'm sure there are tons of people out there far more artistic than I that could do this better, but it's a start.  I do have a problem in that I am not sure how to upload the files needed.  If anyone can direct me I will upload them immediately.
