How can I extract large images from PDF file with A-PDF Image Extractor?

I just downloaded a PDF file from a tourism website and I like the images of beautiful sceneries as well as other fancy treasures. I want to collect these nice looking images but I don't know how to extract them. Besides, I just want the large size images because the small size ones are too small.
