Two years ago I found myself writing a photo gallery application for a custom CMS that allowed you to upload, crop, caption, group and sort your photos for the site’s online galleries. I remember thinking to myself what a chore it was to be reinventing the wheel—there are already excellent free services available that provide this functionality. I wanted the ability to have my client use Picasa to manage his galleries, and view them via SlideShowPro (SSP) on his site. At that time however, support for Picasa’s RSS feeds was not available in SSP.
