SmugMug is a fee-pay digital photo sharing website, founded in 2002. You can create online photo albums, share, store, organise and print your photos. It should be noted that the service is not free. There are three levels of membership: Standard, Power, and Pro. Power and Pro level users can customise their site. Pro users can mark up their prints for sale, (the photographer gets 85% of the markup over the base photo price). SmugMug allows the upload of an unlimited number of photos for all account types.
Flickr is an image hosting service, and online photo management & sharing application. As well as being a site to share photographs, Flickr is widely used by bloggers as a photo repository. The basic service is free, and once signed up you are allowed a 100 mb of free storage space every month: However, images are restricted to 1024 x 1024, and being less than 5mb in size. The only thing to remember is to set the privacy controls that determines who can view the images.
