Tnx in advance!

No problem, it should just be:

$avatarurl = str_replace('&type=thumb', '', $avatarurl);

But what Lynne posted above is very important - if you just use this plugin you'll still get small images because the width is being set in the CSS. But if you just change the CSS, you'll get the thumbnail size images stretched to a larger size. (And again, I believe this only applies to avatars saved in the database, not the file system).
