Disclaimer
I release this because I have been able to backup all my photos with it and it has been developed using other open source. I firmly believe that you shouldn't hack into it any more but to polish a little the algorithm because you could really end up scrapping all Tuenti.
The filter at the moment works by scraping all your albums, seeing who has talked there and scrapping them looking for photos where you have been tagged or commented.
The API I was able to find didn't implement anything else to create more logic, so it's up to you.
