You can arrange the images within a drawing, removing or restoring them, and changing their saved location.
Multiple insertions of an image can show different views of the data.
This is especially useful with multispectral and digital elevation model (DEM) data. For example, you could have one DEM insertion with a color map that shows elevation bands and another insertion that shows ground slopes.
The Image Insertions view of the Image Manager toolspace is especially useful for zooming to an image, changing image display order, and editing color maps. You can change the attributes of an insertion, without affecting the image source data.
The Image Data view is useful for creating new image insertions and managing the image data in your drawing.
