Get rid of automatic resizing for avatars?

[Nicole-Studios]

<div class="author_avatar"><img src="{$useravatar['image']}"height="150" width="150"alt="" {$useravatar['width_height']}  /></div>

That ^
Needs to be this

<div class="author_avatar"><img src="{$useravatar['image']}" alt="" {$useravatar['150_150']}  /></div>

OR this

<div class="author_avatar"><img src="{$useravatar['image']}" alt=""  /></div>
