1. flickr

Flickr is the largest photo sharing website in the world with a huge user base. The website gives users a list of options to upload and view images. The unique feature about flicks is that it lets people create communities online based on photo sharing. Flicks recently upgraded to an HTML5 photo uploaded and organizer which has enhanced the photo viewing experience manifolds.

With a $24.95 a year Pro account you get unlimited full-resolution online storage for your photos. The only problem with flickr is weak people tagging. In spite of that we all would unanimously agree that flickr indeed is the best way to upload your photos online and also for getting in touch with likeminded people.
