# This is like the the file_link tag, but specifically for images
# Identify the image by its label {{ cms:image label }}
#
# `class`   - any html classes that you want on the 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"
