Here's some text from a web-site.

DIGITAL PICTURES ON CD

What are the differences between Photo CD and Kodak Picture CD?
Eastman Kodak developed Photo CD and Picture CD to deliver and store high
quality digital image files of pictures taken with conventional cameras
and
film. Photo CD was introduced in 1992 and is intended for professional and
commercial applications while Picture CD came to market in 1999 aimed at
the average consumer. Generally speaking, Photo CD discs store images
using
a proprietary file format (Image Pac) in, depending upon the version, five
to six levels of resolution (128 x 192 to 2048 x 3072 or 4096 x 6144
pixels). Picture CD, on the other hand, employs the more common JPEG
format
in one resolution (1024 x 1536 pixels). In terms of capacity, Photo CD
discs hold approximately 100 images and additional pictures can be added
at
later times. With Picture CD, however, images from a single roll of film
are written at the time of original processing only. In addition, Photo CD
compatible computer software is required to view and use Photo CD images
but Picture CDs include on the discs a range of Windows and Macintosh
applications to display, organize, enhance and email images.

What hardware is required to view images on Photo CD and Kodak Picture CD
discs?
Both Photo CD and Kodak Picture CD discs are written in industry standard
multisession (Mode 2, Form 1) format and are therefore playable on most
computer CD-ROM drives and MultiRead-compliant (or other CD-R compatible)
DVD-ROM drives and recorders. Historically, Photo CD images could be
displayed on TV sets connected to dedicated Photo CD and multi-purpose
Compact Disc Interactive (CD-i) players. These devices, however, are no
longer available. Most recently, a few DVD-Video player models have come
along incorporating Picture CD viewing capability.

OpenVMS only understands MODE 1 CDROM and cannot handle Mode 2 CDs.

That what you see.
