Bootstrap 3.7.7-beta1
Image Handler 5.3.5


In Admin->Configuration->Images

IH large images maximum width
and
IH large images maximum height

are set to 'empty', also tried '0' and '1024', but when clicking the product image on the product page, it does not display as the size in my images folder which is 1024px.
Example here: https://www.usconverters.com/rs232-r...nverter-xs201a

Any ideas why?
