AOL is shutting three data-storage services, including one of the Internet’s earliest photo-sharing sites, as it seeks to cut costs and focus resources on its advertising opportunities.

AOL Pictures, the year-old media-sharing site BlueString and the online backup service Xdrive will likely shut down by year’s end, though the company is looking to sell at least Xdrive, which AOL bought in 2005 for an undisclosed fee.

Company officials denied speculation Friday that the closures were meant to prime AOL for a sale. AOL parent Time Warner Inc. has been in continual discussions with both Yahoo Inc. and Microsoft Corp., though the talks have been preliminary.
