Is there a way to send a JPG with Jasmine NodeJS?

I'm trying to test out my API using FrisbyJS (which sits on top of Jasmine for Node). I was wondering if anyone knew how to submit/send an image using Jasmine?

http://frisbyjs.com/

My current code is...

var frisby = require('frisby');

var URL = 'http://localhost/api';

frisby.globalSetup({
  request: {
  headers: {
   'Content-Type': 'application/x-www-form-urlencoded',
   'Accept': 'application/json',
   'api': 'key'
  }
 },
 timeout: (30 * 1000)
});

frisby.create('submit an image')
  .post(URL + 'image', {images: '@test.jpg'}, {method: 'POST'})
  .expectStatus(200)
  .afterJSON(function(cart){
    console.log('made it!');
  })
}).toss();

And I get the following error:

  1) Frisby Test: submit an image
[ POST http://localhost/api ]
  Message:
   timeout: timed out after 30000 msec waiting for HTTP Request timed out before completing
   Stacktrace:
    undefined

    Finished in 31.458 seconds

And yes, the image test.jpg does exist in the same folder :) as the spec file and where I'm executing the spec itself (jasmine-node .).
