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. TeachText and SimpleText cannot open very large
files.
Working with Photo CD images in other programs
There are several ways to open and work with Photo CD images in other
programs:
m You can choose a program that automatically opens a Photo CD image
when you double-click it. See “Setting Preferences for How Photo CD
Images Are Displayed” earlier in this chapter.
m From the Slide Show Viewer, you can transfer a displayed image directly to
another program, without copying and pasting. See the next section,
“Transferring the Displayed Image to Another Program.”
m You can copy and paste an image. See “Copying Images From a Slide
Show” later in this chapter.
Once you’ve opened an image in a program, you can change the image and
save your changes on a hard disk or floppy disk. (The images on the Photo
CD cannot be changed.)
