Several people have asked for the ability to exclude certain photos from the top of the home page. People are tired of some, or find one inappropriate for their workplace, or they just personally don't want to see it.
It would be impossible to create a generic filter that would appeal to everyone, so we now have this solution:
If you don't want to see a photo on the home page, click it to go to the photo page and give it a rating of ONE or TWO stars. From then on, that photo will not be shown on your home page. Instead you will see a blank spot and text that tells you why.
