round borders?

a while ago, i made a post about how i could do round borders on my pictures, someone replied with a link, this link showed the difference between an average tutorial on how to do them compared to a better one, there was 2 screenshots of a sharp border and a smooth border, i've gone back quite a few entries and tried looking through the memories, i can't find it anywhere.

does anyone have the link?

nevermind, i found it; http://90miles.livejournal.com/1211.html
