floor plan in blender

When I open up blender I choose top view, background image, i find the image i want (floor plan) from my desk top. but when jet press enter it not inserted as it is in countless tutorials…

Any idea why?

If from the default file you press numpad7 to go into top view you will still be in perspective view. For background images to show you need to be in orthographic view. Toggle between perspective and orthographic with numpad5 or from the View menu
