There are so many free software online and offline to extract selected pagesad from a PDF file. One among them is pdfshaper free. It can do lot more.
Download and install a free photo management tool I'm not going to recommend a particular one out of the box, it's more about what you want to use (or want to use) than it is the tool itself. Photo management tools are great to have if you've had experiences with some other ones, and you want to try something new. A free tool that I've used is Acrobat Reader 11. Acrobat Reader has a really fantastic photo viewer. Acrobat Reader is not a video player. You can't play video of PDF files! That is, you can't play video in Acrobat Reader 10 or 11 and view PDFs. In Acrobat Reader 11 you can now select an individual item page from a PDF and you can view it in full-screen mode.
