How to change avatar size in memberlist?

[Darkrad]

I couldn't fight how to change it but it seems forum makes all avatars 70x70 there (my forum standart is 100x100
),  I would like to make it 50x50 or maybe smaller. How can I do that?

In memberlist_user_avatar

replace {$useravatar['width_height']}

with width="50px" height="50px"

Change it in Member List settings group: Maximum Display Avatar Dimensions

Use this method instead of Ashley1's solution.
