I tried to modify images for different drop-down product variant.
System allow me to upload new images for some one drop-down product variant however it not show up in front end.
If I click update all images in product option area for drop-down replased with default product image.
Is it known issue or I am missing some steps?
I can not find 'drop down image modificaton' in manual.
Can anyone help.

thank you.
