Same with me, I had forgotten about that...
The largest-size pictures are several megs each (or used to be - these are not so bad!), and I was finding, when I hosted copies, that they slowed down the site and ate my bandwidth pretty quickly. (Even some thumbnail files are that size - I re-save them slightly compressed for significant savings.) I do download and keep the large images though, in case I want to crop a closeup for parts pictures.
bml87 has embedded them directly from the official site, so if you want them, save them to your local storage - they will disappear eventually. However, glad you did so, Boris, to show us, for the time being!
