I just recently added this app for Picasa and I really like it.

It’s very useful to upload iPhone photos to Picasa, and you can create a new album from iPhone.
It is very easy to operate, so no special explanation is needed.
By the way, Picasa is very useful when I post photos on my blog.
I used to upload my photos to my own server, but through frequent changes in blogging tools, I’ve come to the conclusion that it’s better to use another company’s photostream for my blog photos, although I often use Flickr as well.
Picasaを使ってる人には絶対オススメです。
