In my opinion the best way to do this is by email. You can use mostly any onoine email provider. Gmail, hotmail, Yahoo mail etc. Just attach the Image files and send them to yourself. If you have a lot of pictures I would reccomend using Google's Picasa. It will let you send more pictures faster and more easily.
