If it matters so much to you, take that image set and do exactly as DanBC suggested. Create a site with all the different image formats out there with a larger test set. Be willing to take matters into your own hands and change the norms and traditions in that field of study. The best way to accomplish that is by offering something better. I would say that a wiki with many test images for many algorithms is something better. If you do an good job, people will adopt your approach and tradition will change. Complaining on HN isn't going to change tradition. Introducing new ideas usually is usually more successful long-term approach than "book burning" because you disagree with the content.
