One of the things I really dislike about PDF is the inability to copy things out of the document. Images are a good example. You see an image in a PDF document that you want to copy out and you can't.

If you need to copy an image out of a PDF document, there is a program called "Some PDF Image Extract" that allows you to do this. Just go here http://somepdf.com/some-pdf-image-extract.html and install the program and you'll be copying images out of PDF files. A quick note about the site that hosts this software... the site is really lame and filled with ads. It almost looks like a scam site, but it's not. The program really works. Just hit the "Downloads" button near the top of the screen and you'll get a page that has a link to download the program you want.
