Washington: Google has reportedly released a tool that allows users to automatically back up photos stored on their PCs to the search giant`s social service Google +.
The Google+ Auto Backup offers users to transfer photos from Mac and Windows machines running Picasa software to Google`s social service.
According to Cnet, the new tool involves an update to its earlier-era Picasa photo software, which lets OS X and Windows users edit photos and upload them to Google`s Picasa Web Albums site.
The new tool, called Google+ Auto Backup , copies photos from users` pictures folder and from cameras or memory cards connected to the computer to Google+ photo service.
Users get to choose the resolution of their pictures for upload from full-resolution images, which count toward Google`s online storage limit or downsampled versions a maximum of 2,048 pixels on edge, which can be stored in unlimited quantities.
