"This is what happens when you play with Lincoln Logs too long."
Aha! Figured it out. File name was too long. Blogger doesn't get my mother's sense of humor. I went to my computer and changed the file's original (huge) name to "stackowood" before I uploaded it, and Houston, we have liftoff. Now I'm going to go change the my file's name back. I like Mom's title better.
