notlaura thanks for your response.
I have had to physically go back and re-import each image to each entry to get them into the image library so that they load as thumbnails on the thumbnails page.
In the post archive the images show up if you click the title of the entry…so far I have only gone back a couple years. Here is an example of a page with no thumbnails:
https://blog.pfleghaar.com/?cat=4&paged=12
as apposed to:
https://blog.pfleghaar.com/?cat=4
It must have been some issue with moving the files from my type pad blog to the wp blog which my media temple server did automatically.
