I migrated Magento from 184.108.40.206 to 2.2.5. After this migration I can't add new image for some products Could you tell me what is wrong?
The image directory path should have already been carried over from your 1.9.X installation. all you should have to do to add the images back is copy over your media/ directory on your old installation into pub/media/ in your new installation.
from here flush your cache and re deploy your static content and your images should appear:
rm -rf pub/static && php-7.0 bin/magento cache:clean && php-7.0 bin/magento cache:flush
php-7.0 bin/magento setup:static-content:deploy
