Closest I could suggest would be to add a class/style to all of your images to clamp them to the screen's dimensions, so they don't spill outside the page. I often use something like:
Code:
img {
width:100%;
max-height:100%;
object-fit:contain;
}
Sometimes I'll change the max height to 80% or so if you want to leave some room for a caption. But if you've got images that are floating left or right, varying widths and so forth and there's no existing styling, you may have to go through it manually and add a few of your own classes.
