Edit: The issue has been fixed (see latest post in this thread).
Hi! Pictures should be showing up. Please make sure you are not launching the game using a shortcut. After unzipping/unarchiving the game, you should have a file called "Tarus Infernal Pledge.html" and two folders called "img" and "music". Can you check if you have images inside the "img" folder?
As a final thing to check is your browser. The game opens in your default browser, but will work best with an up-to-date Google Chrome or Firefox on Windows.
Let me know if you still have issues!
