== About those images == 

 Hi.  Indeed I'm in fault regarding those and some other images.  I haven't yet gotten around to them because I've had limited time to edit, which is worsened by the fact that the website keeps crashing every five minutes.  In the cases of those images, I got them in the special website setup by the Brazilian Olympic Committee during the 2004 Olympics.  The images published there had a promotional/divulgation purpose, and were not tagged with copyright disclaimers.  I believe that the website is gone now (will double check that though), but it was a very singular situation, since images such as those are usually the property of news agencies and/or photographers.  They were posted during the Olympics as part of a day-by-day coverage of the performance of Brazilian athletes in the games.  I will go about adding those explanations to each image's page asap.
