For those travelling, away from their system or otherwise in need of a quick photo upload, Picasa Web Albums now let you email in your album additions.
To enable email uploads, from your Picasa Web Albums account, click on settings and scroll down until you see the Upload Photos by Email section as seen in the screenshot here. Check the box, then type in a secret word. The secret word becomes the suffix on your address in the form of
[email protected]. Then you'll want to add your upload address, like
[email protected], to your email client to prevent head-scratching later on. Really convenient: The subject line of your email chooses the album your pictures jump into. Emails without a subject or with a subject that doesn't match an existing album are dumped into your generic drop box. Emails are limited to 20MB in size, but there's no restriction on the number of files you can send.
