I have created a photo gallery, it was quite easy for me to do with the aid of Google Picasa. To check my photo gallery , Click the Photos link in the top navigation bar. I have made the slide shows with the auto code generated by Picasa. Followed the steps mentioned below.

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:

3. Click Embed Slideshow.
4. Choose your slideshow settings, such as image size, captions, and autoplay.
5. Once you’ve chosen your settings, copy the resulting HTML code (Ctrl-C).
6. Paste the HTML in the source code for your site (Ctrl-V).

This feature is very helpful having easy galleries instead of Static Image Folders which according to me is not an attraction in this Web 2.0 Era. Have a look at my Photo Gallery and you decide Static Image Folder Gallery Vs Flash based Slide Shows.
