Various cloud storage services have different social networking capabilities for sharing images. If you want to share photos on Google+, then Google Drive is your easiest option (no surprise) since Google+ photo sharing is built in. SkyDrive users can post photos directly to Facebook, LinkedIn, Twitter, and email from SkyDrive's Web interface, although your friends will have to visit SkyDrive to see the full-size versions.

Dropbox allows you to share a public link to photos, but in my tests this function didn't work particularly well with Facebook and Google+. Another option is to use Flickr to share photos via Facebook, Pinterest, Tumblr, Twitter, and email; again, your buddies will have to visit Flickr to see the full-size version if you share on Facebook.
