## Usage


### Helpers

#### amp_image_tag(source, options)

##### Url with image's dimensions

    % amp_image_tag('http://sample.com/image.jpg', width: '40', height: '40')
    #=> '<amp-img alt="Image" height="40" src="http://sample.com/image.jpg" width="40" /></amp-img>'

##### Url without image's dimensions

It's going to access file dimensions.

    % amp_image_tag('http://sample.com/image.jpg')
    #=> '<amp-img alt="Image" height="400" src="http://sample.com/image.jpg" width="400" /></amp-img>'

##### Carrierwave

    % amp_image_tag(Article.find(1).thumb.icon.url, width: '30', height: '30')
    # => '<amp-img alt="Icon placeholder" height="30" src="https:g/s3-ap-northeast-1.amazonaws.com/foo/assets/placeholders/icon_placeholder.png" width="30" /></amp-img>'
