Adding an image to the bottom right of my footer

Hey there, I’m very new at wp and making a website but I am trying my best and learning a lot in the process so please be gentle ??

I would like to add an image to my bottom footer either in the right hand bottom corner or centered and along the bottom under the widget “about us” “terms of conditions” info, whichever is easiest, I’m not too fussy in which one.

I have a child theme set up and/or I have a custom css plugin activated.
I am using The Vantage theme.

Thank You in advance for any help anyone can offer.

Here is my website: https://www.scrapbookingdelights.com.au/

I have the image in my footer at the moment but it is there with a widget and is not low or right enough for what I wanted.
