Even if you know nothing about Flash, with BannerZest you'll be able to create really snazzy Flash presentations with your pictures.
BannerZest is a very slick application which makes Flash photo presentations easy. Simply drag and drop pictures from your images folder to the timeline into the order you want them to appear. iPhoto and Photo Booth are already integrated into the program but for other folders, you'll have to browse to them using the file browser at the bottom of the media library window.
Using the Settings window you can add all manner of effects, themes and animations. You can add a title (although it should be easy as double clicking on the 'Title' word but it's not), add subtitles and borders to make your presentation look swish. Once finished, you can share it via FTP or upload it to a website. Note that it doesn't work with OS X 10.4 but an older version available on the developer site will do.
The price of upgrading to BannerZest Pro might put many off although the Lite version is cheaper and produces equally impressive results while lacking some features.
