Editorial Note: Pixel Pipe no longer transmits the location of the image at the time it was taken but rather the location at the time the image was transmitted. Pixel Pipe can still be a useful tool for students, if that can transmit the images immediately after taking them. (06/23/2010)
If you are a lone geotagger with an iPhone, you have many options (iPhone apps) for publishing your pics to the web.
I've experimented with a few photo-sharing applications, but I seem to keep coming back to PixelPipe, a service and an application for publishing pictures to a number of photo-sharing websites. PixelPipe's website boasts, "Publish photos, video, audio, text and files on over 100 online destinations and counting...". It is impressive! PixelPipe can run on Apple iPhones, Google Androids, Palm Pres, and several others. They've also created photo-sharing apps (or plug-ins) for: Firefox, Picasa, Google Talk and more.
This is a great way for the solo geotagger to make quick work of publishing images to a photo-sharing website that supports geotagged images, like Flickr or Picasa Web Albums. You can even tie PixelPipe to your Twitter account to automatically tweet about your newly uploaded pics.
The screenshots above are from PixelPipe running on an iPhone 3GS (publishing to Picasa Web Albums). Enjoy!
