How can I migrate the images of my products from Magento 1 to my Magento 2?
I'll use the official migration tool of the Magento.
All media files (images for products, categories, the WYSIWYG editor, and so on) should be copied manually from your Magento 1 install
media folder to your Magento 2 install
However, do not copy the .htaccess files located in the Magento 1 media folder. Magento 2 has its own .htaccess that should be preserved.
I just had a look at the official documentation, and it says that you can't do it - sorry :)
