Managing layered images

Adding nontransparent layers to an image
increases its file size. To conserve disk space, you
can delete layers, merge two or more layers, or
flatten all layers in an image into one layer.
To track file size:
Check the values in the Document Sizes box at the
lower left corner of the screen (Windows) or the
image window (Mac OS). For more information
on displaying file size, see "Changing image size
and resolution" on page 46.
The first (left) value indicates the size of the file if
flattened. The second (right) value shows the
estimated file size of the unflattened file, including
any layers and channels.
To track the use of the Adobe Photoshop
scratch disk (temporary disk space used
for storing data when RAM is insufficient),
position the pointer over the triangle at the
bottom of the image window, hold down
the mouse button, and choose Scratch Sizes.
(See Using RAM, scratch disks, and system
virtual memory in the online guide.)
