I have to resize the product gallery images.

I'm using this link to resize image
Resize Image

but it's only allow to resize image product_base_image. While I have to resize all other image then base image.

I'm getting all images by

$images = $_product->getMediaGalleryImages();

it's give me images data as

Array

(

[value_id] => 3424

[file] => //w/b/wb01-black-0_1.jpg

[media_type] => image

[entity_id] => 14

[label] => 

[position] => 3

[disabled] => 0

[label_default] =>

[disabled_default] => 0

[video_provider] => 

[video_url] => 

[video_title] =>

    </media>

</view>

You can mention image sizes with their XML entity name in the view.xml file

product_page_main_image
product_page_main_image_default
product_page_more_views

step 2: Run the CLI command from the Magento root.

sudo php bin/magneto catalog:images:resize

Note: Depending on your requirement you can delete other media XML entity like bundled_product_customization_page, cart_cross_sell_products etc
