I like to make sure the books I post have complete edits and that they have all 3 image sizes. Which I used to do from the edit page. But now the three images at the bottom of the edit page are gone. So now I have to go to two different pages, first to edit the data and then to another page to see if it has a small, medium and large image?

Gayle, the site administrators are working on the images section of the website, so at this point the images have been separated from the Data edit page.  So, for now, the answer is yes, you need to go to two different pages currently to edit data and to edit images.
