Yes, Magento 2 Marketplace Mass Upload module does support multiple images upload for a single product. Firstly, create the image zip file.

And then, you can add the multiple images of a single product using –

• CSV File – You can add the multiple images of a product separated by the comma. Make sure you use the same image name you have saved in the image zip file.

• XLS File – You can add the multiple images of a product using image paths like catalog/folder_name/file_name.png(extension). Make sure you use the same image name you have saved in the image zip file.

• XML File – You can add the multiple images of a product separated by the comma. Make sure you use the same image name you have saved in the image zip file.

Note:

• You can upload an unlimited number of products in a single file.
• It supports PNG and JPEG image type.
