Why each option
The client needs a storage medium for image files that allows adding new data and viewing existing data but prevents modification of existing data.
CD-RW (Compact Disc-Rewritable) allows data to be written, erased, and rewritten multiple times, which does not prevent changes to existing data.
"Disk" is a general term (e.g., hard disk, floppy disk) and typically implies rewritable storage, which allows existing data to be changed.
Flash memory (e.g., USB drives, SD cards, SSDs) is rewritable storage that allows existing data to be changed, which is contrary to the requirement of not changing files.
WORM (Write Once, Read Many) media, such as certain optical discs or archival tape, is designed to allow data to be written once and then read multiple times without being altered, fitting the need to add and view files but not change them.
Concept tested: WORM (Write Once, Read Many) media
