I would like to suggest adding in an Image Upload field type with admin-specified allowable file types. This was something I remember having in Drupal and it would open the doors to a lot of things I'd like to do with the Resource Manager. I know you can add images to resources already, but allowing multiple image upload fields for specific usage would make it more flexible when you need to display specific profile ID data (or hide it) in templates using conditionals. It also would be nice to specify image dimension requirements (and validation) for these custom image fields. And make it so only one image upload field is displayed by default for the user, with an option to add more.
Actually, just a generic File Upload field type would be best, not just limited to images.
