Installing and using the Chrome Extension
Firstly, head over to the Move Your Photos extension page and install it.
Once the extension is installed, you will notice a small Picasa icon to the right of the Chrome address bar, near the wrench. Click on this icon and you will be presented with a link to login to your Facebook account. This will grant the extension access to the photos on your Facebook account.
After you have logged in, the extension will start fetching all your Facebook photos. If you have any empty albums on Picasa, the extension will also notify you of this and allow you to delete them.
Once the pictures have been fetched, you can select which albums or individual photos to upload to your Picasa account. Note the guide used to indicate which photos have been uploaded (green border), which photos are in the queue (yellow border), which photos are not to be uploaded (grey border) and which images are altogether unavailable (red border).
Unfortunately, the extension appears to be limited to fetching the photos you have uploaded within specific albums. So, all your albums, mobile uploads, profile pictures, and wall photos are included. However, tagged photos are not included. Once you have decided which photos to upload, select “Upload” from the bottom of the page. You may have to scroll down if you have a lot of photos. The upload process will take some time depending on the number of photos you have selected.
Once all the photos have been uploaded, they will appear in segregated albums on your Web Picasa account.
The album is set to private by default and only those with a link to the album will be able to view the photos. You can now choose which of your circles to share the photos with.
Conclusion
This app is useful if all your photos are stored on Facebook but you feel like switching your allegiance to Google+. It would be a lot more useful, however, if it was possible to upload all your photos (including tagged images) from Facebook to Google+. It is likely, that there are privacy settings that is blocking this type of functionality.
