[Plugin: People Lists] Thumbnail Resize ?!

Hallo,
people List is a greate plungin.
But i have some problemes with my templates.
For my site i need to manipulate the thumbnail size.
The default template size is 96px 96px and this is to big.

I try to minimize the thumbnail with some div box expressions but in the image tag hast the 96px fix.
`<img height=”96″ width=”96″ class=” avatar avatar-96 user-2-avatar” alt=”” src=”https://URL/wp-content/plugins/user-avatar/user-avatar-pic.php?id=2&w=96&radom=1294839997″&gt;
I want to greate simple list width an little picture, name an email adress but i don′t find any css oder img code to manipulate the image size.

I think the best way is to greate an additional option to %thumbnail%, maybe %little_thumbnail%

But i don′t understand how it works?!

Can anybudy help me.

Thanks
nean
