The 320x280 size of the video makes a screenshot pretty low quality, though I still have some of the original project files and could probably do larger re-renders of some scenes. I did that once for a Flickr account, but they were all from the fake preview (which featured my own corridor set) and I've forgotten my login there.
Edit: Never mind, memory is better than I thought. The bridge scene might work.
I might still have some of the stills I used for the end titles, will have to check what's on this hard disk.
Sending you a PM for another source with screenies from the main story.
