My wife and I take a lot of photos during all our trips but most of them never end up on our webpage due to lack of a good system for putting them there. Does anyone know of a tool that allows us to synchronize some folders on either our PC or Mac to a remotely hosted website using ftp?

The ideal setup would be to have a folder with subfolders that would contain all of the photos we want to publish and through the push of a putton, they would all get uploaded to the web server with an index and thumbnails created automatically.
