You are on the backup site for Any posts, moves, or other changes you make here will not be permanent, because the pages and database from the main site will be backed up here every midnight EST. Additionally, things may not be working right, because this site is also a testbed for newer system software. So, if you are not here to test, develop, or merely read this site, you may want to change .org to .com in the navigation bar and go to the main site.

While the right-shifting was more readily apparent, I also checked for vertical shifting by creating a position where a Rook covered a whole file. What I found is that there is also downward-shifting. No matter whether the board is rotated for Black, the empty gifs in the lower right are closer to the lower right corner than empty gifs in spaces more to the left or top. This is consistent with right and down being the two directions that increase as the x or y position of the image increases, since 0,0 is in the top left corner.
