I was watching this video https://www.youtube.com/watch?v=MydQrXzsE4k&t=333s

Where the person traces a image of a jet plane. I was trying to do something similar but the first step is to import a tracing image. My software doesn't have that function, when I go to file>import my only options are image, DFX, STL. The video has a 4th option called tracing image. I don't have that option. I tried image and that is not what I wanted.

I have looked through a bunch of tutorials and sifted through all the toolbars and I cannot figure it out.

How do I import an image to trace?
