If you get the email working just right, good for you.
Let me offer up my favourite alternative. It is a third party solution, and some people don't like that.... it is what I use. Maybe you'll like it.
A website called posterous.com, you can sign up with them, and they'll give you an email link. You configure any sites you would like to post to (I do my WP site, flickr, twitter, and facebook)
You send an email to the address they give ya, and your email is automatically posted to whatever sites you have configured. The reason I like them, is that they work with photographs and music and stuff too. So I can send thema photo from my phone, and it goes to all my sites.
