7. Pinterest

We know Pintrest is not essentially a photo sharing service but it is an effective way to upload photos and share them on the different networking sites such as Facebook, Twitter etc. it is simple and free to use.

The drawback is that it can be difficult to navigate at times. Also it does not work well with Google Chrome browser. Users can join only by invitation and some areas of interest are not well populated with content. But it is a new and efficient way to share photos.
