Thanks for letting me know! It has been fixed. The server had 08-01 & 08-10 confused, so the first two pages of 08-01 repeated.
Here is the short version of the explanation why from my webmaster;
The problem is that there is a space after the 1 and 2 in the files names when they were saved in the scanning process: 08-10-73D p1 .jpg & 08-10-73D p2 .jpg. The server is set up to look for the closest matching file name, if it can't find the correct file name, so 08-10-73D p1.jpg (for example) comes back as a closer match (on the server) to 08-01-73D p1.jpg than to 08-10-73D p1 .jpg. Anyway, I changed the html to look for a space after the file prefix. Generally the server makes the right choice, but in this case it didn't.
Evidently I need to pay more attention when naming scanned files, which is very good to know before I take on another multi-page project.
