# This is how you link previously uploaded file to anywhere. Good example may be
# a header image you want to use on the layout level.
#   {{cms:file_link id, as: image}}
#
# `as`      - url (default) | link | image - how file gets rendered out
# `class`   - any html classes that you want on the result link or image tag. For example "class1 class2"
#
# - variant_attrs are not functional, perhaps due to some change in ImageMagick
# - Simply use a class in your CSS / SASS to style your image display
# `label`   - attach label attribute to link or image tag
# `resize`  - imagemagick option. For example: "100x50>"
# `gravity` - imagemagick option. For example: "center"
# `crop`    - imagemagick option. For example: "100x50+0+0"
