# Portal transform for images with captions
#
# Transforming a non-standard field type to html on output is
# probably a better way to do things than the original transform
# which converts html to a non-standard field type.
#
# The transform is the same as the one done by html2captioned, but
# this version expects to work on text/x-html-raw
