Sharing Photos Online
Facebook – Is the most popular social sharing site, although more aimed at social interaction rather than just portraying photos.
Instagram – is becoming one of most popular sites for just sharing photos, but they are limited to a square format and designed mainly for uploading from smart phones.
Flickr – is a popular free photo-sharing site – recently bought by Smugmug
Google Photos – You can set up photo albums but only share them to people with Google + accounts.
Photobucket – is a photosharing site which is free with adverts or $10 a year with no adverts. Good for editing photos.
Smug Mug – is an excellent photosharing site. It costs US$40 a year but has a great display interface and the option to sell photos. Currently I think this is the best Photosharing site.
Shutterfly – a free photosharing site – one of the first that was available.
