Basepack holds the most of the images. update pack+html has the latest pictures added, and the html file, which is the actual game itself. what you want to do is extract both packs, and merge the "pics" folder from the update with the "pics" folder from the basepack. Afterwards, as long as you have the html file in the same folder with the merged "pics" folder, you should get the images to appear when you play the game. To check, once you start the game and confirm you are 18+, you should see 2 check marks.
