Clouds on the horizon

I have update the free pictures resource with two cloud pictures. The first of the two pictures is a classic cloud picture and not so much more while the other one has some pretty good sun rays going on.
I have also made some changes on how the pictures on the front page are shown, the pictures list now also contains promoted pictures, i.e. pictures that I think deserve a second chance to be seen on the fron page.
More pictures are on the way, pictures of a blue butterfly.
