Even though you pictures don't work, this is not tollerated due to the fact that a majority of the Halo community hasn't even had the chance to play on the maps yet. There are some people who would like to find the skulls on there own and if your pictures did work you would make these people quite angry. I believe Bungie even said not to show the locations of the skulls until March 3rd.
Sorry, IDK they work for me fine. If you do not have the maps, you don't have to click the button. Its your choice. EDIT: SORRY PICS ARE NOT WORKING and BTW I did not take the pictures. EDITx2: Replaced non-working pics, with links to the shots.
