If you get a Google+ account, one added benefit is that you can now upload an unlimited number of higher quality photos (up to 2048 x 2048 pixels) to Google+ and/or Picasa Web Albums, for free. There are some differences in how your photos are handled and stored, depending on if you upload photos in Google+ or in Picasa Web Albums. The details are explained here.
Using the desktop software version of Picasa, you have the option to sign in to Picasa Web Albums to upload and share your photos. If you get a "login incorrect" message when you try to sign in to Picasa Web Albums from the desktop version of Picasa, it may be because you have 2-Step Verification turned on in your Google account.
Google’s 2-Step Verification is an optional and relatively simple way to provide an extra level of security for your Google account. While it is not a newly introduced feature, it may not be very widely known or used by most. More information on 2-Step Verification for your Google account is given below, including details on how to setup and use it.
On SugarSync, the online file backup and synchronization service, all users can now get up to 625 MB in bonus storage for free.
