Select Viewport Image
Display > Select
Viewport Image
Description:
The Select Viewport Image (Display > Select Viewport Image)
command will select the background image, if any, in the current
viewport, allowing you to edit its position, orientation, and size with
the standard geometry manipulators. To avoid unwanted selection while
modeling, this is the only way to select a viewport's background image.
Once selected, the image can be edited using the regular Move, Rotate, Scale, and
Universal manipulators, allowing you to position it as desired. It can
also be edited with the Numerical Editor (Modify > Numerical Editor) for
precise positioning.
Notes:

> Set Viewport Image...) window help file.
