The aim was always to rate the images by both quality and subject, so a great looking mallard or other common species would get 5 stars alongside a less-than-perfect osprey grabbing a fish out of the water. What we never planned for was someone giving a grainy blackbird 5 stars, because the photographer had given their out-of-focus robin 5 stars the day before
I think we may just go for some sort of 'pick of the week' page with 50 great shots chosen by the gallery editors. That way we can show of some of the best pics and also change the 50 every 7 days.
