Using Picasa to resize photographs

When I build a website I have to reduce the size of  photographs so that they'll load quickly and easily in a web browser. I normally use Adobe Photoshop Elements to do this.
However, if you don't have this software on your PC, why not use Google's Picasa software, which is available to download free of charge. Go to http://picasa.google.com/ and follow the instructions.
There are numerous tutorials on the web to tell you how to resize photos  (search for "picasa resize image"), such as http://www.latech.edu/tech/rural/website%20project/web_tutorial/articles/resize_pictures_picasa.html . The help within Picasa is good too.
I use Picasa when I want to resize several pictures at once, such as when I want to load up photos to an online gallery.
