Oh wow, glad you liked it.
To get the originals you can get them by using a URL like this:
http://www.envoid.com/image/id-4036
Just replace the ID of the photo (you can see it in the path). Or really, just remove "/fpThumb-large" from the URI of any photo.
With this set you'll get some tiffs, fairly large ones, and since I scanned slides, you might need to remove some dust.
Thanks.
