I understand this might not be the best place to ask this question...
I have an application that's sending important html documents to my Kindle. They are displayed all right, but all referenced resources (css, images etc) are not there.
I don't really care about absent css, but having images is crucial for me. Even though sometimes they are absolutely referenced, they are not displayed.
I tried to send a zipped archive with the html file and all images it references, but Kindle interpreted it as separate documents instead.
P.S. I'm sending the documents via Amazon's free @free.kindle.com e-mail.
