After you add options (for a product) - then "variants" will appear in the edit product menu... you can click on that and add variant images there...
i.e. you add product option first e.g. option 1 = "Colour" with choices "blue", "green" and option 2 = "Size" with choices "S", "M", "L" (do this first)
Then "Variants" will appear and under that will be
Variant 1 blue S
Variant 2 blue M
Variant 3 blue L
Variant 4 green S
Variant 5 green M
Variant 6 green L
You can then add a different photo for each variant.
