{{- /* The img shortcode creates <img> tags proxied through imageproxy.

Site parameters:

    params:
      imageproxy:
        url: "http://proxy.example.com/" # absolute URL of imageproxy instance
        default_baseurl: "http://example.com/" # optional baseurl configured on imageproxy
        always_sign: false # always sign proxied image URLs
        always_b64: false # always base64 encode proxied image URLs

Shortcode usage:

    {{<img src="image.jpg" options="300x200,r90" class="right">}}

If the imageproxy.always_sign parameter or the "sign" attribute on the shortcode is true,
the image URL will be signed with the key in the IMAGEPROXY_SIGNATUREKEY environment variable.
Options must be in their canonical form for signing to work.

    {{< img src="https://external/image.jpg" sign="true" >}}
