My workflow is now as follows:
- Copy the pictures from my digital camera (currently a Canon Ixus 300 HS) to my mac with Iphoto. Iphoto puts the pictures into new events (= pictures taken at the same time of the day)
- Then I select the pictures I like and put them into an album of Iphoto.
- Next I export the album on Picasa Web using Picasa Web Albums Uploader, selecting "Actual Size" so that it archives the original files in the cloud. This may take a bit longer for uploading but will save the day when all my pictures disappear from my mac and backup.
If I manage to fill up the 20 Gigabyte, it can upgrade to 80 GByte/ year for 20 dollar/year. So that's save for the future ;-)
