To further suggest you held back a better solution because you assumed the PHP developer was too stupid to understand file hashing is both another insult and bad practice.
It wasn't a better solution. It was one of many alternatives which came to mind; but I offered them the best solution (serve the graphs from a PHP script) and the easiest solution (run a cron job to delete the old graphs).

Using PHP is a choice, it's not innate. You are not defined by the programming language you choose to be.
It doesn't matter if there's 10 or 10 million PHP developers, it's still insulting. You sell a product online, and you've now alienated a large developer community. I'll never recommend or sign up for tarsnap now.
