Picasa still has the 1 GB specification as if you see the FAQ page but if you use Google + to upload the pictures instead of directly uploading it to the web server via you computer then your picture wont be a part of the 1 GB space. Instead it would be counted as free. So indirectly this is unlimited storage on the picasa web albums for all those who tend to go ahead for the services of Google +.
So you are you waiting start to upload pictures via google +
