My apologies for the confusion. I've answered this a few times already, but I lose track of where, so I've updated the game description on the game page.
These images will not be in the final game. There are missing images, and some of those missing images (mainly late-stage broodmothers, background images, map, and item images) use placeholder images while the rest of the character art is being finished, which is currently around 70% done.
