You can increase redrawing speed by hiding or unloading images you inserted
using the Insert An Image command that you do not need in the current
drawing session.

Overview of Hiding, Unloading, Detaching, and Erasing Images
When you insert an image using the Insert An Image command, AutoCAD
Map 3D stores information about the image in the drawing, loads the image
into memory, displays it onscreen, and locks the image file on the disk.
NOTE This command does not affect images you added using Data Connect
(page 440).
You can increase redrawing speed by hiding or unloading images you do not
need in the current drawing session. Hidden images are not displayed or
plotted; only their drawing boundaries are displayed. You can choose to hide
an image regardless of the current viewport coordinate system. If you no longer
need the image in the drawing, you can erase a single instance of the image
or you can detach the image to erase all instances of the image and the image
information.
Aside from locking the image file, none of these actions modify the original
image file itself.
