So before I disable all the games that have either a broken image or a broken download link, can I just check that still having a broken image link means the download link is also broken (so nobody was able to download it and create their own screenshot)?
I've edited the imagecheck and downloadcheck pages to include a link to PM the author on the forums, or to email them. This obviously only applies where someone has been credited for the game, which isn't always the case. I also added
http://www.adventuregamestudio.co.uk/site/games/bothcheck/, which only shows games where BOTH image and download links are marked as broken. All these pages are now only accessible by games pages updaters, since there's private email addresses included.
