Assuming that you already are a StrangeBarfly, the next thing that you need to do is Sign up for Flickr. Flickr has a mobile tools page that has instructions specific to your phone.

If that doesn't work, remember that most phones support sending email. Flickr will post whatever photos you send to your account.

So there are two modes, the moblie version of Flickr, and posting to Flickr by email.

If you use another photo service, tell me about it, and I'll see about getting support for it.
