Answer 1

Product images are cached while saving the product from admin panel. However, sometimes you may need to re-create the product images cache after you import products, if images were resized manually in the cache, or if the cache was manually cleared by mistake.

Command :

php <magento install dir>/bin/magento catalog:images:resize

This command takes no arguments or options,The message Product images resized successfully. displays to confirm the command succeeded.
