I think they are birch trees (Betula), based on the white bark with black horizontal patterns (Lenticels). The bark patterns at the base of the trees are also very similar to birch. Either way (relating to one of the comments), it's an autumn picture, where both birch and aspen have yellow leafs (aspen leaves can also be red or reddish, especially at the end of branches).

This page also agrees with me (which doesn't necessarily have to mean that much though), which labels the exact same picture as "birch-tree-wallpaper-3.jpg".

I'm not sure about the exact species, but I know that there are North American species where the bark can shift between white, pink or reddish. One possibe suggestion/pure guess is Betula neoalaskana, but as you can see from the wikipedia page this species can also hybridize with Betula pendula and other species. To me, it doesn't look exactly like the Eurasian Betula pendula or Betula pubescens, which I'm most familiar with (those are the two species found in Sweden).
