Ok, here's my code:

        /* Start Image RESIZE */  

        $navigator_user_agent = ( isset( $_SERVER['HTTP_USER_AGENT'] ) ) ? strtolower( $_SERVER['HTTP_USER_AGENT'] ) : '';   
    if (stristr($navigator_user_agent, "msie")) {   
        return '<a href="' .  $link . '" class="highslide" onclick="return hs.expand(this)" ><img src="' .  $link . '" border="0" alt="" style="width: expression(this.width > 640 ? 400 : true);" /></a>';   
    } else {   
        return '<a href="' .  $link . '" class="highslide" onclick="return hs.expand(this)" ><img src="' .  $link . '" border="0" alt="" style="max-width: 800px;" /></a>';   
    }    
/* End Image RESIZE */

As you can see the code is fine... but as MissKalunji said, i DON'T want small pictures to get into the resizer's way. I want them to be ignored by it... is it possible?
