I am sorry but I cannot give you any permission to use the collage of hands you asked for. The photos aren't mine, I only made a mosaic from them. The mosaic is for use on Flickr only. I have no permission from the photographers to let others use their photos.
Therefor you cannot use the mosaic without the exclusive permission from all the photographers from the photos in this and other mosaics.
Created with fd's Flickr Toys.
Thanks to all the photographers who made it possible for me to make this beautiful mosaic.
