Replacement Avatar hook code

[Bilderback]

EDIT: I originally had a question on an avatar replacement and found the working code.

postbit_display_complete

PHP Code:

if ($this->registry->options['myproduct_avatar_replace'] == '1')
{
$myreplacement = 'http://myurl.ext/image.png';
$myavatarheight = $this->registry->options['myproduct_avatar_size'];
$myavatarwidth = $myavatarheight/2;
$aviwidth = 'width="'.$myavatarwidth.'"';
$aviheight = 'height="'.$myavatarheight.'"';
$this->post['avwidth'] = $aviwidth;
$this->post['avheight'] = $aviheight;
$this->post['avatarurl'] = $myreplacement;
}
if ($this->registry->userinfo['showavatars']) 
    {
$show['avatar'] = true;
    } 


EDIT:
Sorry, I got it working.My code was returning the post[aviheight] and post[aviwidth] as integers without the image attributes surrounding them.
