Optimize when multiple copies of identical image are stored in PDF

[Ndolam]

Recently a financial institution I deal with has replaced the small JPEG logo at the top of every page with a much larger PNG image (about 20 times as many bytes in the image). If that isn't bad enough, they include a separate copy of the image for every page of the document.

I don't see any way to ask my current version of pdfsizeopt to remove all but one copy of the image, and just reference the same object whenever it is needed.

As an enhancement, would it be possible to add the ability to detect redundant image objects, delete all but one, and modify the references to deleted objects?

Thanks.
