First thanks for your comment and detailed description!

To solve this problem I wrote a word counter..

/* Function by AMIS to limit words */
 function AMIS_Wordlimit($text,$limit="10"){
        $exp = explode(' ',$text);
        if(count($exp) <= $limit){
                if(count($exp) == "1" && empty($exp[0])){
                        return "No bio was found for this author yet...";
                }else{
                        return $text;
                }
        }else{
                for($i=0;$i<$limit;$i++){
                        $string .= $exp[$i].' ';
                }
                return $string.'...';
        }
 }

This should limit the words displayed in the bio, and should stop it from being messed up in low res.

Added this code for our Author spotlight

  <div class="AMIS_Authors">
                <div class="AMIS_title">About the author : <a class="websnapr" href="<?php the_author_meta('user_url');?>"><?php the_author_meta('display_name') ?></a></div>
                <div class="AMIS_main">
                        <div class="left">
                                <div class="image"><?php userphoto_the_author_photo() ?></div>
                        </div>
                        <div class="right block title" valign="top">
                                <div class="bio"><?php the_author_meta('description') ?></div>
                                <div class="links">More by <?php the_author_posts_link(); ?></div>
                        </div>
                </div>
        </div>

And for the time being the following CSS.

.AMIS_Authors {
  position : relative;
  border : 1px solid #AAA;
  background-color : #EEE;
}

.AMIS_main {
  width : 100%;
  height : 134px;
  position : relative;
}

.AMIS_main .left{
  padding : 2px 2px 2px 2px;
  border-right : 1px solid #AAA;
  left:0px;
  top:0px;
  width : 130px;
  height : 130px;
  position : absolute;
  z-index : 1;
}

.AMIS_main .right{
  left : 135px;
  top : 0px;
  width : 85%;
  position : absolute;
  z-index : 2;
}

.AMIS_main .right .bio{
  height : 70px;
  max-height:80px;
  font-size : 14px;
  padding : 10px 0px 10px 10px;
}

.AMIS_main .right .links{
  padding : 10px 0px 10px 10px;
}

.AMIS_title{
  padding : 2px 0px 2px 5px;
  font-weight : bold;
  color : #FFF;
  font-size : 17px;
  background-color : #D11;
  width : 100%;
}

.AMIS_title a:link{
  color : #FFF;
  text-decoration:none;
}
.AMIS_title a:visited{
  color : #FFF;
  text-decoration:none;
}
.AMIS_title a:hover{
  color : #FFF;
  text-decoration:none;
}

Hope you guys like it
