[Plugin: Simple Local Avatars] arrowchat integration

Hello,

I’m using arrowchat and wondering if anyone could help me integrate simple local avatar with it. Currently, arrowchat is pulling gravatar images even if users uploaded their own image using this plugin. In my arrowchat integration.php I have this line which is responsible for displaying the user avatar:

function get_avatar($image, $user_id)
	{
		return "http://www.gravatar.com/avatar/" . md5($image) . "?d=identicon";
	}

I understand that i need to point it to simple local avatar but just plain clueless how to do it as I’m no php programmer.

Anyone can help me here?
