It's Easy For Me ;-)
Since my name is "Caska" and i have many issues of Berserk (the manga she belongs in) on my computer,
i can just go through, and cut out new icons from time to time,
or i can change them up to suit my mood.
It IS much like changing clothes
update 2009: OFC now ive changed my name to Shierke- which is still a character in the Berserk comics- so the changing CAN be as frequent though i seem to have a favorite one for her.
