not a real big deal but a lot of images even in the photography section...their c-index have dropped, my highest image in the perms of an 88 went to an 82, and it is about a year old, and the dandelion field drom from a 99 to a 94 and it is a very old image from a few years ago, why is this, and how come the scores are going down on older images whether archived or permed
