Additional Identification on Ideas Portal Photo

Would like to easily identify the type of customer who's submitting ideas through a visual marker (e.g. a colored stripe across the bottom right corner of the photo). We have a number of types of users and would like to badge them differently (e.g. our employees, expert customer, etc.). It'd be great to set this up/manage this through the API at the very least, but photos are missing from your APIs. It'd be even better if this option was part of the ideas portal configuration.
