When trying to share images amongst other Cad programs. Other programs, such as Agtek, will recognize the limits of the image as a bound. By being able to snap to the corners, I can quickly make a rectangle that represents the boundary of the image and I can add this to my CAD file that I send off. Saving time on the next user.
Exporting images with world files is another way to do this (possible in TBC but not officially released).
Minor issue but does help when transferring data.
