Take another look at the google cached version. You'll see the yearbook cover there. You can also go read the heavy article and see full pages, including one showing Ms. (Blasey) Ford. And then see the same content and some pictures in the redacted version.
Where are these full pages of which you write? I can't see anything but text in the cache. Certainly, no images of Chrissie.
There are 32 images in the cache. All except the first one (the yearbook cover) are advertising added by the putrid platform (issuu.com).
Down at the bottom of the cached document is an array of links to individual pages (7 to 305). But they all 404 (as does the main link, of course).
If you want to see how the Putrid Platform works for a non-deleted yearbook, see here. There is a viewing box in which you can view page images (similarly to that other internet pestilence Scribd). There is a Download button which does not work. Most of the browser window is taken up with non-content stuff, leaving text and pictures small and hard to see. It's an overall dreadful experience. A simple PDF would be far, far superior.
If you look at Google's cache of the working yearbook, you will see that it looks similar to the cache of the Holton Arms yearbook. Lots of text but no content images. At the bottom there is an array of links to pages. However, these are not to page images, but merely land you looking at the issuu.com viewer positioned to the specified page. I suspect the purpose of all that text is to allow Google to find the content.
I had been under the misimpression/assumption that the deleted yearbook was a PDF file. It's not. It's a proprietary document format, not an internet standard. Google actually does a decent job on caching genuine PDF files. It turns them into HTML page images (example).
