Today, there is a good news for you guy who usually spend few time on Picasa Community to share your own pictures with others. From now onwards, you can upload multiple files simultaneously. I think Google should have updated this feature sooner than they have just done.
Selecting multiple pictures from a folder and then uploading them to the web is not an innovative feature. Many other services even free players have already helped end-users, particularly non-tech uploaders share their pictures more easily.
