In order to import image as 3D planes in Blender, we’ll need to adjust some settings. Load Blender and head over to the Prefernces. To do this go to File > User Preferences.
In the User Preferences, go to the Addon Tab.
Type in Image in the Search Section. Enable the Import-Export: Import Images As Planes addon by clicking on the little box on the right.
Hit Save User Settings at the lower left side of the window and Restart Blender.
Now onto Importing Images…
Go to File > Import > Images As Planes.
Browser over to the File that you want you import as and Blender will now load the image as a 3D Plane with the aspect ratio of the image. That’s It!
