After much frustration it looks like the folks at Google have fixed whatever was broken, because for a full week now all of my photos have been showing.  I don't know what they did or what was wrong, but it's working so I'm thankful. 
I'm heading into a week for meetings followed by a week of travel, followed by Thanksgiving, so I doubt much will hape this month, but I look forward to continuing the migration from my old blogs to this site.
