I just figured out that not only can you upload multiple pictures to a Picassa Web Album, BUT you can do videos as well. This will change you a HUGE amount of time. So you can just upload a whole set of pics/videos and walk away. Then just link the album to your blog!
You could have albums already linked so you only do this once then just upload it.
For example, Mike and Mrs. M can give their parents a web based photo album. It can sit at the grandparents house a link to a Web album so as they baby grows they just upload latest pic to that album and grammy and grandpa see pics automatically.
* I will be trying out the new wi-fi enabled SD cards that automatically connect to a web album... so you won't even need to upload them they will automatically do it on their own.
