At least you found them :)
I'm lucky enough to have a defined folder for that so I know which names to add to my resource list. Which I really need to update again. It's been a while and I found a couple of new image archives.
I think I've learned by now :)
Now I'm making screencaps, because I realised I didn't have any of the Blind Banker and I wrote down Mrs Hudson for close up... no suitable screencaps in any folder. Now I just need to decide if I want to start the second episode in 10 minutes and let it run until midnight or if I do it tomorrow (which probably would feature the unaired pilot as well - and maybe some of that making of)
