My colleague Ellis Hamburger and I took a look at 10 top services for backing up your photos online in an effort to find the best. My favorite of the bunch is Everpix:
Everpix tries to hook you with nostalgia, borrowing a page from Timehop. Each day, the service will send you a “flashback” of photos from a year ago. You can also trade photos inside the service using “photo mail,” which will add specific pictures to a friend’s Everpix collection automatically. Its website loads incredibly quickly, and offers several views for browsing your photos, including a gorgeous timeline that loads photos in reverse chronological order as you scroll, and a view that only shows photos it has imported from Instagram or Facebook.
