just wondering if you can solve this problem have been bothered me for some time .

as i am importing this product from somewhere with woocommerce .

https://kitmochi.com/product/sample-product/50pcs-Personal-Protective-3Ply-Face-Mask-Covid-19-Corona-Virus/

example if i am using plain permalink from setting which is Plainhttp://kitmochi.com/?p=123
and the product permalink will be http://kitmochi.com/product/sample-product/

with this setting , i will be able to view my all my photo inside description .
if i change other permalink format , it will not be displayed

basically the image location is saved as <img src=”wp-content/uploads/2020/03/50pcs-Personal-Protective-3Ply-Face-Mask-Covid-19-Corona-Virus-details-1.png” in description .

if i were to add url , it will works . example https://kitmochi.com/wp-content/uploads/2020/03/50pcs-Personal-Protective-3Ply-Face-Mask-Covid-19-Corona-Virus-details-1.png
