Showing several pictures in a web application by selecting checkbox options

I am creating a web-based (HTML, CSS, Javascript, VueJs) anatomy tool. I have a list of body parts as checklists. I also have a body image that gets its organs added to it when clicking on the checklist.

For example if you click on the "Left-Hand" option on the checklist then left-hand will be added to the picture of the body.

Now I want to know:

1-How do I put the body part pictures in the place and angle that I want them to be in.

2-How to setup the code so by clicking on the checklist, the respective body part is added to the body image?
