With Picasa, it is not easy to select photos when they are not in the same folder. However, this operation is necessary to easily handle several pictures at the same time, to publish on your web album or print them for example.
- Open the first file in the Library of Picasa.
- While holding down the Ctrl key, click on the picture to select.
- Photos added to the frame selection in the lower left. Click Save Selected Items.
- Open the second folder and select in the same way (Ctrl) photos.
- The pictures are added to the tray. Keep them and do the same with other folders.
- You can then apply any command at all the pictures of the selection.
