And now I will probably have to program a “Picasa” tool that will automatically upload new photos to the web. However, I still have not decided which service to use for it.
So far I have 1. a Picasa account for private photos, to which I keep adding new ones, 2. a Picasa account for public photos, to which I keep adding new ones, and a WL account for one-off albums & images/photos that I did not take myself, both public and private. I already have libraries for WL SkyDrive here (but I have not tried them yet), and uploading to Picasa is easy by e-mail. So I think I will not bother with it and will upload only to Picasa..although having an automatic uploader for WL as well would not be bad either :/
