console.log client.image() is undefiend and client.images() crashes server #6

I am trying to log out the images on a webpage and it does not work.

I have tried. 

console.log 'client image ' + client.images()  // Crashes server

console.log 'client image ' + client.image() // undefined

Here is the code I am using:

client = new MetaInspector('http://cnn.com', {})

client.on 'fetch', ->
  console.log 'client image ' + client.images
  console.log 'client links ' + client.links().join(",")

client.fetch()

console.logging out client.description() & client.links() seems to work fine.

The image() is undefined because cnn.com does not provide an meta[property='og:image'] property.

line 4 on seconds block should be client.images() because it is a function. I will update the README file. If everything works as expected close this issue.
