#### `Post()` object and posting

`Post` object is used to represent a post on D*.

##### Posting

Posting is done through a `Stream` object method `post()`. It supports posting just text, images or text and images.

`Stream().post()` returns `Post` object referring to the post which have just been created.

##### Text

If you want to post just text you should call `post()` method with `text` argument.

    stream.post(text='Your post.')

It will return `Post` you have just created.

##### Posting images

Posting images, from back-end point of view, is a two-step process. First, you have to upload an image to the desired pod. This is done by `_photoupload()` method. It will return id of uploaded image.

Then you have to actually post your image and this is done by appending `photos` field containg the id of uploaded image to the data being sent by request. This is handled by `post()` method.

`post()` has two very similar arguments used for posting photos. They are `photos` - which takes id and `photo` - which takes filename.

You can post images using either of them. Even passing them side by side is accepted but remember that `photos` will overwrite data set by `photo`.

Example #1: using `photo`

    stream.post(photo='./kitten-image.png')

Example #2: using `photos`

    id = stream._photoupload(filename='./kitten-image.png')
    stream.post(photos=id)

The effect will be the same. To either call you can append `text` argument which will be posted alongside the image.
