John,
That would at least let me clean up any custom image sizes I had going on.
Based on that…in theory…a possible but complex solution would be to:
– Turn off all the normal “reserved sizes” in the WP Media section under Settings.
– Recreate them all as Custom Sizes in functions.php.
– Setup the remove_image_size for the unnecessary ones when uploaded based on the ACF field.
– And then I would have only the necessary images for the slideshows.
Thanks for your idea!
