For screenshots you might have visited Androsy's Homepage which was founded around Mach 18th, 1999. Though at the time there were many screenshots, the site unfortunately has lost them all. Most of the site's screenshots were moved to WoT when Androsy shut down his site on October 1st, 1999.
The types of screenshots you would have found would be the monster section which features snapshots of many of the game's creatures. If you went to the Places of Tibia section, you would find screenshots of the city, North Dungeon, and Wurmtemple. The events section was mainly filled with wedding photos, but some other curious events where listed. There was a good vs evil battle which was more of a friendly fight between several players who made new characters to battle each other with LMMs. Also, there was a statue pushing contest where two players pushed their own statue from east gate to the sorcerer's guild in Tibia City to see who could do it the fastest. For the spell section I am unsure what might have been in here as the section is long lost, but it was likely many mage spells showcased. The miscellaneous section of course has a few random screenshots that didn't fit else were. When Androsy closed his site, the content for it moved over to WoT. I have saved what I could and placed it in the Events section.
