Before viewing the contents of a Photo CD
Normally, you open Photo CD images with the SimpleText program that came
with your computer. If you wish, you can use a graphics or image-editing
program instead of SimpleText to open images. For instructions, see the
“CD-ROM Discs” topic of Macintosh Guide, available in the Guide (h)
menu. If you use SimpleText to view high-resolution images, you should
increase the amount of memory that SimpleText uses. For more information
on memory, see the “Memory” topic of Macintosh Guide, available in the
Guide (h) menu.
A note about resolution
When a Photo CD image is created, it’s recorded at five different levels of
resolution. The higher the resolution, the more information is recorded about
the image, and the sharper the image appears when displayed or printed at
larger sizes. However, high-resolution images take up a lot of memory—up to
18 MB of data for one photograph—which affects file size, as well as the
amount of time it takes to display or print an image.
It’s best to work with a resolution appropriate for your monitor or printer.
Some monitors and printers cannot display or print very high-resolution
images.
For most work, a resolution of 768 x 512 pixels or smaller is suitable. For
detailed work or very high-quality reproductions, you may want to use a
higher resolution.
Make sure to open high-resolution images with application programs designed
to handle large image files. SimpleText cannot open very large files.
Sharing a CD-ROM disc over a network
You can share a CD-ROM disc using the file-sharing feature of System 7.5. If
the disc has audio portions, you will be able to hear the audio yourself, but
other people on the network will not. Likewise, you cannot hear the audio
portions of discs you access over a network.
For further information about file sharing in System 7.5, see the “Sharing
Files” topic of Macintosh Guide, available in the Guide (h) menu.
