It’s possible for images to change when a multi variant option is selected. To achieve this:
1) The ‘parent’ product row must always contain an image (the first image that eBay displays is the first you list – other can be separated by a comma in the same column in the spreadsheet import).
2) The ‘child’ sku rows can contain images (ordered in the same way you wish them to be displayed and separated by commas in the same column of the spreadsheet import).
See attached file for example:
