FULLWIDTH and Full Height page

using the default template, fullwidth page layout I am trying to have a 2848 x 4288 image display fullwidth ad full height.

I add a row
set to stretch row and content( no padding)
set full height row to “yes”

fullwidth section set to enable

added FULLWIDTH SECTION element

not sure WHERE i need to add the image and what if any other elements i need to use.
