One of my customers is a Blogger customer and a Mac user.  On my machine, a Windows computer, I can upload pictures to her Picasa Web Album easily.  However, she is a Mac user and cannot upload to her Picasa Web Album or see it to manage it online.

So I searched for help on this and found this in the Picasa help files (http://picasa.google.com/support/bin/answer.py?hl=en&answer=12569):

While Picasa isn't currently available for Mac OS, we do offer two tools for Mac users to bulk upload photos and videos to Picasa Web Albums:

To use either of these tools, please read these instructions, then visit our Mac Uploaders page and click Free Download. The download includes an installer package containing both the Exporter and the Uploader. If you'd prefer not to download one of the uploaders, you can upload photos individually with your web browser.

 

Hope this helps!
