Yeah, I had to delete the images to ensure that I could zip everything...
I reinserted all of them, and when I did, the only thing off was the navigation w/ the next/prev arrows below the thumbnails.

As for the preloader, I did try both methods w/ the ctrl/enter (twice) and the standard test method, and the error screen came up. The same error message comes up again when I click on the different buttons in the file: bio, portfolio, etc.
