However, the image files themselves couldn't be copied over.
So take the images you had in MijoShop and copy them in the images/com_hikashop/upload folder and you'll get your images associated with your products automatically.
I did that, but, seems to me that problem is Mijoshop saving images in folders related to categories.
Example; have product Child bike and that product is category Vehicles -> bikes ->child bikes
The image for that product is located in folder Mijoshop-> Categories -> Vehicles -> bikes ->child bikes
