HI @swifty
I’d be more inclined to use a True/False field. You can then do something like:
<?php if ( get_field( 'display_watercooling' ) ): ?>
Your image goes here
<?php endif; ?>
So using an True/False field called ‘Display Watercooling’, if it’s then ticked, the predfined image is shown. If it’s not ticked, you could either show another image (add an ELSE clause) OR not show an image at all.
