The text is phrased, so you can change the text using the core. But if you want to change the text for each image, this is exactly how CAPTCHAS are solved with automation (that would be very bad design, and we would be back at the same problem as Q&A...the bots would solve them). The text should never indicate what the image question relates to (unless you want bots to get through)... Please mention enhancements in threads rather than reviews, it's much easier to communicate there.
