@totallytech,

There are 2 ways you can accomplish adding new fields, this can only be done by using the Image Store Hooks.

1. add new tags and substitution values. Values and substitution must be in the same order, use these 2 hooks:
ims_default_opts add values to the $options[‘tags’] array.
ims_substitutions add values to the $substitutions array.

2. modify the entire message (email).
ims_admin_message
ims_customer_message
