My product images were duplicated after migration. What should I do?

Some shopping carts besides large product images also include thumbnails. In most cases, both standard product images and thumbnails are the same. But in some cases, Target shopping cart doesn't support thumbnails, so after data migration there may appear duplicated images.

In order to prevent this use free additional option:"Skip product thumbnail images migration". It allows not to migrate thumbnails in case they are the same as large images.
