OK - a solution to this is a separate hack:

In includes/functions_showthread.php:

Find:

PHP Code:

        if (empty($avatarurl) OR ($bbuserinfo['userid'] > 0 AND !($bbuserinfo['showavatars'])))
        {
            $show['avatar'] = false;
        }
        else
        {
            $show['avatar'] = true;
        } 


Add below:

PHP Code:

        if($avatarurl)
        {
            $avatarbits = getimagesize($avatarurl);
            $avatarimgsrc = $avatarbits[3];
        } 


In postbit / postbit_legacy:

Find:

<img src="$avatarurl"

Add after:

<if condition="$avatarimgsrc">$avatarimgsrc </if>

HTH mate - this puts the width and height properly formatted for the <img src tag - if you want to format it using style, then you would use $avatarbits[0] and $avatarbits[1] for width and ehight respectively and then format your $avatarimgsrc statement accordingly

$avatarimgsrc = "style="width:$avatarbits[0]px;height:$avatarbits[1]px"
