OK, I don't see what this has to do with iText though.

That's a different question.
The first question is about storing thumbnails extracted from
JPEG2000 files in a CMS as images; as far as I understand there
is no PDF involved. You just need smaller size images (both in
appearance and file size).
The second question is about showing thumbnails in the Pages Pane
of Adobe Reader. In this case, you can either count on Adobe
Reader to show the thumbnail automagically (for instance: if
the image spans the complete page, you don't have to do anything;
Adobe Reader does it for you).
Or, suppose each page has an image and some text, but you want
to make sure only the image is shown in the Pages Pane, you could
use the method you described. I'm 99% sure that if you reuse the
same Image object you used to add the Image to the page, the
Image bytes are present only once in the PDF file (but I should
check this).
The first question is off-topic on the iText mailing list;
the second question is on-topic.

Bruno
