Inserting an image in AutoCAD is simple so lets start.
Go to Insert then Attach.
Or you can type "IMAGEATTACH".
From Files of type choose All image files if you want to insert an image of course and select your image which you want to insert.
There also some different files you can attach.Click Open.
You will get this window and just click OK.
Then it will ask you to specify your insert point and scale.Do it.
Your image is inserted and as you can see you can change contrast,brightness and so on.
That is it for this tutorial :)
