Getting a image into the background for reference

Hi all I’m having trouble getting a background image into my scene. I have atutorial but it looks like things have changes since it was made
Any help would be appreciated

This tutorial works with current versions of blender http://cgcookie.com/blender/2010/03/15/using-multiple-background-images-in-2-5/

N while holding mouse in the 3d viewer…holly crap THANK YOU I feel like I just went from skiing green to blue that cured a few things for me…

cant wait for the black diamonds…ok I know its spring but but I didnt get enough skiing in this year…

cheers

From a quick scrollthrough I don’t think this was mentioned - you can drag and drop images into the 3d view to set them as background images.
You can also set Empties to display images, which can be very useful. Like background images, they remain visible in wireframe mode.
