Hi, this is a pretty basic question but I'm not entirely clear how to do this.

I am trying to use a third-party service that has web-based service. The service is called Postful. But I'm not clear what exactly to do?

I've looked at ActiveResource (http://api.rubyonrails.org/classes/ActiveResource/Base.html) and rest-client, but I'm still not clear exactly what steps, code, and files to create.

I'm trying to use Nestful but I'm not entirely clear how to make this work. http://github.com/maccman/nestful

http://www.postful.com/service/mail is one of the services (details found http://www.postful.com/developer/guide#rest ), but to upload an image I have to post the following (but I'm not sure how I actually do this?). Thanks!

> http://www.postful.com/service/upload
> 
> Be sure to include the Content-Type
> and Content-Length headers and the

> request.
> 
> POST /upload HTTP/1.0 Content-Type:
> application/octet-stream
> Content-Length: 301456
> 
> ... file content here ...
>

> <?xml version="1.0" encoding="UTF-8"?>
> <upload>  
> <id>290797321.waltershandy.2</id>
> </upload>
