emailing images to blogs

can you work out how to email images directly to the blog?
can you take that even further using mobile technology?
how could you use that for a field trip?
would that help you to learn more effectively? if so, how?
do you have tools at home we could use on such a fieldtrip?
can you devise a competition based around a fieldtrip between rooms 5 and 9? for example, a mini-documentary showcasing your learning from the "Mfieldtrip", using phones, cameras, video cameras, email, blogger, etc.
