In reply to Nick Brown - UKC:
Fair enough -I did notice the randomiser thing when I went back through the article.
And once I'd realised that I was being biased by the image size I did go through them all enlarged. But if I had been voting as I went through the article first time round it would have been too late to change my votes by the time I'd realised that I was being biased by the size (and I did totally change my favourites in all but one class when all of the pictures were a similar size!)
I know you can't make the images exactly the same size, but stopping the fifth image of each class being approximately twice the size of the previous four should be possible?
It might just be me though, so feel free to ignore!
