If you don't want to use Google's online Web space to store your photos, you can upload them to your own personal Web site's FTP server. Right¬click on the album you want to upload and select Export as HTML Page. Enter a name for the album title and the resolution that you want to export the images to. Click Next, choose a template from the list and click Finish. The finished page will be displayed in your default Web browser. You can upload that folder to your site and create a link to it from your main page.

There's a feature that Google claims as experimental but it allows you to upload the photos to the FTP server directly through Picasa. Go to Tools > Experimental > Publish via FTP. Again, select a resolution, a save location and a template. Now you'll be prompted to select an account. Click on Account Manager to create a new account. Click Add an Account and enter your FTP server information-address, user and password-and click OK. Now you can select your new FTP server and click OK.
