Tap on each thumbnail of the photos you want to upload, then click on the Upload button at the bottom.

Tap on the Uploading message, and you can see more details and even cancel the upload process.

To get to this screen, tap on one of the thumbnails in the Photo Selector. You can navigate back and forth through the list of photos by dragging the current photo to the left or to the right.
To upload the current local picture to Picasa, tap the upwards-pointing arrow icon (on older Android devices, press the Menu button and then choose Upload).
This will upload the current picture to your default Picasa album.
