Get the Lowest Prices anywhere on Macs, iPads and Apple Watches: Apple Price Guides updated June 26th Photos beta disappears as users continue to await OS X iPhoto replacement

Without explanation, the beta Photos application is no longer available to access via the website, as a vague "early 2015" launch date for a new Photos for OS X app also looms.

The iCloud Photos app had been available in beta form since last October, when it first debuted. In the following weeks, Apple had gradually added features, such as the ability to manually upload photos to the cloud.

But now, Photos for is no longer available to access. Manually entering the URL for the app returns the error: "Can't load Photos. There was a problem loading the application."

While it may be a temporary glitch, the disappearance of Photos at the start of 2015 comes as users are still awaiting the launch of the new Photos app for OS X Yosemite. Apple has said the new application will become available in early 2015, but has not provided a more specific launch window.

Apple officially ceased development of both Aperture and iPhoto in favor of "Photos for OS X" last summer. The replacement Photos app will feature image search, editing, effects, and third-party extensibility, or plugins.

Photos for OS X is expected to be an in-between product, blurring the line between consumer and professional-grade image editing and management software. For example, while image adjustments like saturation, temperature and contrast exist in iPhoto, the Photos app will have a higher level of control akin to Aperture.

Whether the disappearance of the Photos beta is related to Photos for OS X is unknown.

iCloud Photos, known as iCloud Photo Library on iOS 8, lets users automatically upload photos and video from their Camera Roll for storage and cross-device syncing and download. The feature is similar to Photo Stream in iOS 7, but with support for full-resolution content and edit syncing.
