It's not hacking. There weren't any firewalls to bypass or passwords to crack or anything. My level of ability doesn't reach that anyway, I just looked at the code of the page, it's their fault for leaving it on an open server with no protection.
Technically I'm not breaking the law as I'm not charging for the images, nor are there any copyright notices on the pages. I checked before I linked DK, I'm not that stupid to go posting completely illegal things. I did also post the links for people to buy them.
Also, I'd like to point out that you uploading BBC footage to youtube is illegal.
