Make images required

Hello again.

I am trying to make some of the listing form fields required. I have no problem making text or select fields required.

I can not seem to figure out how to make the image input required.

Is there away make images required. further, Is it possible to require a minimum number of images?

Either of those would do. Thank you.

Also, I would post a link/ticket (will do soon with regards to my other issue) but the site is offline on localhost.
