I have been a Flickr Pro for many years and have now added a Smugmug website as well. View at https://photorrhorne.smugmug.com
Unlike Flickr the Smugmug site allows for viewers to purchase photos (both digital downloads and prints.
If you are thinking of starting a Smugmug site I have a Refer a Friend discount link … you would receive a 20% discount on your first year subscription (and, if you do buy a subscription I also received a credit equal to your discount). The link is https://secure.smugmug.com/signup?Coupon=qWnTrh
