This is exactly the kind of sales model that helps everyone, though. If this frustrates you then you aren't thinking about it hard enough. The author offers the library that generates these images for free with a GPL license. If you are interested in the end product but don't want to / can't spend 8 dollars you can build it yourself easily thanks to the work the author did and released for free. If you'd rather not break out the IDE or can't then you can give the author a small amount of money to do it for you. Everyone wins. There are no losers in this situation.
