Magento 2 Product base image and thumbnail images are not showing!

Question

Product images are not showing on product detailed page.

Small images are showing on listing page but base images and thumbnail images are not showing on the product page.

I have given 777 permission media folder. Issue after migration from magento 1.9 to magento 2.3.1

How can I fix the issue?

Answer 1

Simply go to product edit page and resave. Is it showing now?

so you need:

php bin/magento catalog:image:resize

Also: Any errors in browser console? or system.log and exception.log?

Answer 2

Delete attributes with the no_selection values using this SQL script:

DELETE `cpev_s`.* FROM `catalog_product_entity_varchar` `cpev_s` JOIN `eav_attribute` `ea` ON `cpev_s`.`attribute_id` = `ea`.`attribute_id` LEFT JOIN `catalog_product_entity_varchar` `cpev_0` ON `cpev_0`.`row_id` = `cpev_s`.`row_id` AND `cpev_0`.`attribute_id` = `cpev_s`.`attribute_id` AND `cpev_0`.`store_id` = 0 WHERE `cpev_s`.`value` = 'no_selection' AND `ea`.`attribute_code` IN ('image', 'small_image', 'thumbnail') AND `cpev_s`.`store_id` > 0 AND `cpev_s`.`value` != `cpev_0`.`value` AND `cpev_s`.`value` = 'no_selection';  

After, don't forget to flush cache
