Let’s face it: we all have a folder full of digital photos that never get viewed, shared, or worst of all - never backed-up. Local apps that manage photos never quite get the job done and typically only accomplish one thing - moving that digital shoe box into a fancy user interface where photos never get viewed, shared, or backed-up. Granted you could probably accomplish those task individually with multiple local apps, but as the complexity increases our desire to follow through with an action diminishes. Fortunately, there’s a plethora of photo web apps that act as an all-in-one solution.

Facebook is a social networking platform, or so they say. Over 70 percent of monthly Facebook visitors spend their time viewing or uploading photos. And with over 21 billion photos uploaded, Facebook has undoubtedly become the de-facto standard for photo sharing on the Web. The team over at Facebook have done a phenomenal job in making the experience as simple as possible.

Flickr is another popular photo web app, and it’s the app of choice for many pro and pro-consumer photographers. Flickr offers a compelling set of features - simple but powerful editing tools, geotagging for photos, and versatile sharing tools. But the biggest draw for Flickr is it’s large community of users. It’s an amazing arena to share and showcase photographs to friends, family, and other photographers. And of course, with unlimited storage it’s a quick and easy way to do back-ups for your photos.

Fotki was built with a similar premise as Flickr. What started as a photo sharing site for a close circle of friends has blossomed into a photo printing, selling, and blogging site. The interface is slick and streamlined and makes browsing public photos fun.

SmugMug offers unlimited photos, unlimited storage, no ads, easy uploads, and sharing - it’s easy to see why it’s an up and coming web app. There’s an option for a Pro account where users can even sell photos as stock art.
