Tune Raster Image Performance
You can reduce the demands on system performance when manipulating large
or many small raster images.
Load and Unload Raster Images
You can improve performance by unloading images when you do not need
them in the current drawing session. Unloaded images are not displayed or
plotted; only the image boundary is displayed. Unloading an image does not
alter its link. If memory is not sufficient to open multiple attached images in
a drawing, images are automatically unloaded.
In the External References palette, you can use Reload to reload an unloaded
image or to update a loaded image by reloading the image from the specified
directory path. If a drawing is closed after an image is unloaded, the image
file is not loaded when the drawing is next opened; you must reload it.
To unload or reload images
1 Click Insert tab Reference
.
2 In the External References palette, in the File References pane, right-click
the image name, and then click Unload or Reload.
The status of the selected image changes.
All instances of the selected attached images are unloaded or reloaded.
To display specific image instances

2 Right-click in the drawing area. Click Properties.
