I am having a similar issue. I am using the “Berlin Theme” and my t-shirt’s left arm and right gets cut out. I tried different codes, but none seem to work on the “Berlin Theme”. On the default theme, “Dawn” two the codes worked perfectly.
I tried your posted solution directly above this paragraph, but I am difficulties finding “product page” and so on.
My issue was I didn’t like how the images became HUGE when clicked on, so thank you for pointing me to the product pages edit. I was bale to change my zoom option so my website works more how I want it to. Thanks!
