All the categories are sub-categories of each other: Valentine Event Images is a sub-category of Event Images and Dragon Matchmaking - 2015 is a sub-category of Valentine Event Images. We do this because some people may have different preferences in looking up images: perhaps they want to see all Valentine event images from all events, or want to browse through all Event Images. The Sprites category also has a ton of sub-categories such as egg, egg sequence, hatchling, adults etc.
