Gallery is by far superior for people wanting to manage on-line pictures, captions, etc. What I was really out for is an "export to Gallery" feature from within iPhoto ... and yes, after a little bit of googling I found iPhotoToGallery. While still in its infancy, it could use some mileage, feedback and help from the macosxhints community. Check it out!
[robg adds: If you haven't used Gallery before, it's a very powerful and flexible PHP-based online image management system.]
