avatar size?

what is the allowed avatar size? and how would you recommend precropping pictures?

update: i got it thank you

I think it's 160 pixels wide by 260 pixels high.

For pre-cropping, just use a simple image editor... PhotoFiltre is lightweight and easy to use for that purpose, and it's free. So, no need to pirate Photoshop just for that.

lol I used Microsoft Photo editor, or Paint

For cropping use http://mypictr.com/ very easy to use and you get good quality (most of the times)
