How to Select and Cut Outline of Image

Hello!

Fairly new to carving, but most of my projects are from images I have found on the internet.

I know about two stage carving, but is there a good method of selecting the outline of the image for the rough cut? I want to be able to cut out an image and then use a V-Bit for the detailed inlays.

Might be a specific app or type of file but I am having issues simply selecting the linear outline of images pulled from internet
