I am trying to switch from xaringan to quarto and I could use some help with a code snippet for the thing I do perhaps the most often in presentations-- have a full-page image with a small attribution (text and/or link) aligned in the bottom corner. Does anyone have such a code snippet?
Here's an example of the code I would use in xaringan:

background-image: url(img/mpls-stp-8.5x11-DakotaMap.jpg)
background-size: cover
background-position: top left
