Execute Hook Location or add code

[Rich]

Hello,

I am not sure if this is possible, but I had an ide. I am using the Journal Modification. Currently, when the call to display the journalpage template is made, it has already called on the avatar by using this code:

		require_once(DIR . '/includes/functions_user.php');
		$avatar = fetch_avatar_url($journalinfo['journalist_id']);
		if ($avatar == '')
		{
		 $show['avatar'] = false;
		}
		else
		{
		 $show['avatar'] = true;
	//	 $userinfo['avatarsize'] = $avatarurl[1];
		 $avatarurl = $avatar[0];
		}

Is it possible to do the same type of coding to call upon the profile picture? I can get the profile image that is in use to display, but I can't get it to change when the user has updated it or deleted it. I know this has to do with the dateline, but I am not sure how that is incorporated.

I was thinking that it may be impossible to insert a hook location prior to the template being called. If this is possible, I am trying to learn WHICH hook to call and how I would call the data in the template.

I am not sure if this is even possible.

I have reviewed the hooks tutorial and I have also reviewed the member.php file trying to see how they handle the profile pictures.

I am not afraid to modify php files, so feel free to get me editting.

I would appreciate any assistance with this. Thanks.
