Custom background-images for radio button css

Question

It is my goal to insert a img into the radio button, but a different image for different radio buttons next to each other (the idea is to select the image that fits with the request). It is part of a form (the selected option has to be sent along with the form).

Currently I'm using the normal input="radio" function with the inserted into the html in the tags. However, using this method I cannot force a "selected" state.

So I guess my question is, can I make it so that the label or radio button have different background images using css? Or is there a different option that I fail to see?

Thanks in advance.

This is a tricky Codepen ( did it in 2 min) might be what you wants (Bootstrap needed)

.btn-group>.btn-group:not(:last-child)>.btn, .btn-group>.btn:not(:last-child):not(.dropdown-toggle) {
