PDF is great. Images are nice sizes and print out crisply and well.
The actual PNG's are rubbish sizes - tiny - they are next to useless for printing out (I wanted to use these png files and print them out individually, using a photo shop program)
This really is disappointing. If you are happy for us to use the PDF images, why not make the PNG's larger and useable as well?
