You can insert any number of raster images into an AutoCAD drawing. Each image is placed in a frame, and a link is created between the drawing and the image file.
When you insert an image with the AutoCAD Raster Design toolset Insert command, you can preview the image and information such as file type, color depth, and density. The column of folders along the left side of the Insert Image dialog box is called the Places List. It contains shortcuts to local folders, such as your Desktop or Documents folder.
An inserted image must be correlated in the drawing. Correlation is simply a means of positioning the image using known coordinates. If you want to display the image, you must also assign it a color map, which specifies how to use the available colors to show image data.
You can configure your inserted image in three different ways during the insertion process:
During insertion, you can change some attributes, such as the image scale, the color of the image frame, and the foreground color of bitonal images. For more information, see Inserting Images.
