Just a quick note to say that the pictures are back online.
As luck would have it, within seconds of my last posting, Amazon's S3 service went down. Amazon provides the storage for Smugmug and Smugmug hosts my images, and that's why none of the pictures were visible.
So if you visited my blog sometime between 10am and 6:30pm MST, please do come back. The pictures are there. I promise. (unless the Amazon gods take them away again)
