How to add this to your web page:
You can embed a Flash slideshow of any web album. It’ll be automatically updated when you make changes to your album. Follow these steps to embed a slideshow:
On the My Photos page, click your album.
Click Link to this album on the right-hand side.
Click Embed Slideshow.
Choose your slideshow settings, such as image size, captions, and autoplay. (most probably 600 pixels)
Once you’ve chosen your settings, copy the resulting HTML code (Ctrl-C).
Paste the HTML in the source code for your site (Ctrl-V). I then usually centre it.
Once the slideshow is embedded in your site, people who click your slideshow will be taken to view your album in Picasa Web Albums.
