not too clear on your question, but if you have found an ebook in your zip file, and you intend to upload it to resell, you only have to upload the pdf as is, or rezip into another zip file, and upload that to your site.
without really having more info on what the problem is, that is all I can say.
Also, depending on the ebook in question, (whether it is a plr, mrr, or other license) you can not rip images from an ebook and upload and post separately, unless it is actually plr. Otherwise, if mrr or of lesser license, it would most likely be against the terms.
hope that helps, if not, please rephrase your question to make it clearer
