When exporting photos and signatures out of Fulcrum, all photos will be contained in a ZIP file as .jpg files.
Inside the record data file(s) there will be a column that contains the photo/signature file name. This file name is system generated to ensure uniqueness.
Note: When downloading the data through the downloader, you will have the option on what you want the data columns for the media to be populated with. You can either choose to have a URL that can be used to view the media within Fulcrum (login required) or the media's unique ID.
In addition to the photos, there will be an additional file that contains the photos EXIF data.
