Every album in Picasa Web Albums is potentially collaborative. This means you can open up your online albums so other people can contribute photos and videos.
Adding contributors
Make an album collaborative by adding contributors - individuals or entire Google contact groups - in either Picasa or Picasa Web Albums. Contributors will need to sign in to their Google Account to add photos. Their content will be attributed to them, and they can make edits such as adding captions to, rotating, or even deleting the pictures that they've uploaded. Of course, as the owner of the album, you have the ability to edit this content as if it were your own.
PicasaIn Picasa, you can add contributors when sharing or uploading photos.
| Sharing: Click the Share button in Picasa, add contributors, and select the box next to 'Let these people contribute to my album." | Uploading: Click the Upload button and select the box next to 'Let these people contribute to my album.' |
