Have you ever needed to insert another instance of an image using the options from the Image dialogue box?  Using the IMAGEATTACH command will allow you to pick the same image, but after the image is selected the command will give an error stating the name can not be used again.

Solution, use the IMAGE command.  This command is not available from the menus, but can be found in the Reference toolbar or by typing IMAGE at the command line.  The IMAGE command will open the Image Manager where you can highlight the image to insert again.  After highlighting, pick the Attach button and the Image dialogue box reveals itself.  You can now use the options available in this box to insert the new instance.
