You can get that type of image from a stock agency .. it just requires purchasing editorial rights instead of royalty-free rights. It will cost $75-200 instead of the $1 you pay here and there will probably be more specific restrictions on its use as well but if you really need it you need to search an agency that is rights-managed and not royalty-free. Hope that helps.
