A couple of months ago, we launched the option to Upload your Public images from Picasa Web Albums into Panoramio. Today we are expanding this option by allowing the upload of Unlisted albums as well.
Private images from Picasa Web Albums do not have this option. To use this feature remember that photos need to be geo-tagged and in a a Public or Unlisted album. This process creates a copy both in Picasa Web Albums and in Panoramio. If you ever want to delete it, remember you will need to do it from both places.
Please let us know what you think in the Panoramio Community Forum.
