Which page? https://pdfcrowd.com/inspect-pdf/ ?
Just upload the PDF, let it analyze it, and then use your browser's search function to find "Thumb".
It's a bit more complex with https://pdfux.com/inspect-pdf/.


I may have guessed wrong about there being no Thumbs in the F16866* file. To my knowledge, Okular will not display thumbnails if 
there are none in the document. But, it does for that file.

What may be the issue is, that file appears to be PDF version 1.4, while the other two are 1.6 or 1.7. Perhaps the thumbnails 
are referenced differently in the earlier version.
