For the forum members to offer guidance we'd need a lot more info. For example how did you migrate the data? Do you have an example of an image that didn't work? Did you test one product before doing the migration? Anything else you think is worth sharing?
If you don't want to uncover why it didn't work - just skip the questions above.
Next step for you would be to then go back and get all the images adding into the products that now exist. Do you still have those images available somewhere? Do you have a list of what the product is on Shopify and what the product is on Magento (so a mapping relationship)?
