With one of these new cellular phones with a camera you can send images to your weblog and do moblogging. If the phone could be connected to a GPS receiver, you could position these images in real time on a map and do a trip blog.

If you, like me, have none of the above technologies, you can still take a picture every few miles and then upload them to your blog. Here's the tripBlog of the Gradisca d'Isonzo - Loreto trip I just did.
