hey frens.. ok the trees pix were actually found under "Images" when i google "lonely trees"
it's from this flickr page: http://www.flickr.com/groups/lonelytree/

it's actually a group photo pool and these are the rules: -
Rules
▪ The picture shall be of a single tree without great disturbance in the surroundings.
▪ Try to aim the picture against the horizon to get a clear view of the silhouette, form and branches of the tree.
▪ No close-ups, we want to see the whole tree.
▪ Tag your picture "lonely tree".

best photos are highlighted on the blog
