Let me just clue you in on a little secret.... the current covers directory is sitting at 37GB with another 15GB in pending uploads. If we get even a handful of people trying to pull down every cover in our collection, i'm going to get a nasty call and probably a massive bill from my hosting provider. That's the quickest way to get the site shut down because I don't have a ton of cash sitting around to pay a massive bandwidth bill. On top of that, if I published the collection on BT, there would be no point in running this site any longer.
Over the years I've had numerous requests for copies of the entire collection or large subsets of it and the reality is that we provide these covers for the community for individual gamers looking to print out missing covers, not for stores. If stores want to use them to print out covers for their missing games, I'm fine with that but it would be quite a bit of work for me to collect the requested covers and arrange for that amount of data to be transmitted and I just don't have the time nor the desire to do it.
I've got backups that run daily and backup to a mirrored array at my house so we aren't in danger of losing our covers. I've also publicly stated that if for some reason we got shut down, I would drop the entire collection out on BT and that would be the end of it.
I admire the enthusiasm around this whole idea, but with a collection this large it really isn't feasible and it changes daily.
