Random Avatar plugin for Joomla/JomSocial - How to diagnose and fix? - php

Question

I'm pretty new at this but I want to learn...
I have a GPL plugin (for Joomla 1.6 / JomSocial 2.6) that I would like to use (w/ Joomla 2.5 & JomSocial 2.8) but it will need some fixing or updating. It should check for a default avatar and replace it with a random one. It installed but doesn't work.
How can I verify it's getting the data it needs?
I think one problem might be no file listed in the database is default. It looks like this plugin expects one to be there.
function onUserLogin($user, $options)
{
$juser = CFactory::getUser($user);
$curavatar = $juser->getThumbAvatar();
$gender = $juser->getInfo($this->params->get( 'genderfield' , 'FIELD_GENDER' ));
if($this->compareEnd("default.jpg", $curavatar) || $this->compareEnd("user.png", $curavatar) || ($this->contains('minisocialgender_images',$curavatar) && $this->params->get( 'reassign' , '0' )))
{
The script is only about 100 lines so I hope someone can point out some obvious problems.
Thanks for looking and any help you can offer. Here's the rest of the script...
